SANTA CRUZ BIOTECHNOLOGY,INC.ER α(MC-20):sc-542Santa Cruz Biotechnology,Inc. 1.800.457.3801831.457.3800fax 831.457.3801Europe +BACKGROUNDEstrogen receptors (ER)are members of the steroid/thyroid hormone receptor superfamily of ligand-activated transcription factors.Estrogen receptors,including ER αand ER β,contain DNA binding and ligand binding domains and are critically involved in regulating the normal function of reproductive tissues.ER αand ER βhave been shown to be differentially activated by vari-ous ligands.Receptor-ligand interactions trigger a cascade of events,including dissociation from heat shock proteins,receptor dimerization,phosphorylation and the association of the hormone activated receptor with specific regulatory elements in target genes.Evidence suggests that ER αand ER βmay be regulated by distinct mechanisms even though they share many functional characteristics.REFERENCES1.Danielian,P .S.,et al.1992.Identification of a conserved region required for hormone dependent transcriptional activation by steroid hormone receptors.EMBO J.11:1025-1033.2.Mosselman,S.,et al.1996.ERb:identification and characterization of a novel human estrogen receptor.FEBS Lett.392:49-53.CHROMOSOMAL LOCATIONGenetic locus:ESR1(human)mapping to 6q25.1;ESR1(mouse)mapping to 10A1.SOURCEER α(MC-20)is an affinity purified rabbit polyclonal antibody raised against a peptide mapping at the C-terminus of ER αof mouse origin.PRODUCTEach vial contains 200µg IgG in 1.0ml of PBS with <0.1%sodium azide and 0.1%gelatin.Blocking peptide available for competition studies,sc-542P ,(100µg peptide in 0.5ml PBS containing <0.1%sodium azide and 0.2%BSA).Available as TransCruz reagent for Gel Supershift and ChIP applications,sc-542X,200µg/0.1ml.Available as fluorescein (sc-542FITC)or rhodamine (sc-542TRITC)conjugates for immunofluorescence,200µg/ml.Available as Alexa Fluor ®405(sc-542AF405),Alexa Fluor ®488(sc-542AF488)or Alexa Fluor ®647(sc-542AF647)conjugates for immunofluores-cence;100µg/2ml.Alexa Fluor ®is a trademark of Molecular Probes,Inc.,Oregon,USASTORAGEStore at 4°C,**DO NOT FREEZE**.Stable for one year from the date of shipment.Non-hazardous.No MSDS required.RESEARCH USEFor research use only,not for use in diagnostic procedures.APPLICATIONSER α(MC-20)is recommended for detection of estrogen receptor αof mouse,rat and human origin by Western Blotting (starting dilution 1:200,dilution range 1:100-1:1000),immunoprecipitation [1-2µg per 100-500µg of total protein (1ml of cell lysate)],immunofluorescence and immunohistochemistry (including paraffin-embedded sections)(starting dilution 1:50,dilution range 1:50-1:500)and solid phase ELISA (starting dilution 1:30,dilution range 1:30-1:3000).Suitable for use as control antibody for ER αsiRNA (h):sc-29305,ER αsiRNA (m):sc-29306,ER αsiRNA (h2):sc-44204,ER αsiRNA (r):sc-45949ER αshRNA Plasmid (h):sc-29305-SH,ER αshRNA Plasmid (m):sc-29306-SH,ER αshRNA Plasmid (h2):sc-44204-SH,ER αshRNA Plasmid (r):sc-45949-SHER αshRNA (h)Lentiviral Particles:sc-29305-V,ER αshRNA (m)Lentiviral Particles:sc-29306-V,ER αshRNA (h2)Lentiviral Particles:sc-44204-V and ER αshRNA (r)Lentiviral Particles:sc-45949-V.ER α(MC-20)X TransCruz antibody is recommended for Gel Supershift and ChIP applications.Molecular Weight of ER α:66kDa.DATASELECT PRODUCT CITATIONS1.Massaad-Massade,L.,et al.2002.HMGA1enhances the transcriptional activity and binding of the estrogen receptor to its responsive element.Biochemistry 41:2760-2768.2.Guo,Z.,et al.2002.Estradiol-induced nongenomic calcium signaling regu-lates genotropic signaling in macrophages.J.Biol.Chem.277:7044-7050.3.McCarthy,T.L.,et al.2003.Runx2integrates estrogen activity in osteo-blasts.J.Biol.Chem.278:43121-43129.4.Perissi,V.,et al.2004.A corepressor/coactivator exchange complex required for transcriptional activation by nuclear receptors and other regulated transcription factors.Cell 116:511-526.5.Omoto,Y.,et al.2005.Estrogen receptor αand imprinting of the neonatal mouse ventral prostate by A 102:1484-1489.6.Pedram,A.,et al.2007.A conserved mechanism for steroid receptor translocation to the plasma membrane.J.Biol.Chem.282:22278-22288.7.Klein,C.,et al.2010.Transcriptional profiling of equine endometrium during the time of maternal recognition of pregnancy.Biol.Reprod.83:102-113.ER α(MC-20):sc-542.Western blot analysis of human recombinant ER α.<ERα116K -80K -52K -35K -30K-ER α(MC-20):sc-542.Immunoperoxidase staining of formalin-fixed,paraffin-embedded human breast carcinoma tissue showing nuclear localization.。
A群链球菌抗原检测试剂盒使用说明书
A群链球菌抗原检测试剂盒(胶体金法)使用说明书【产品名称】通用名称:A群链球菌抗原检测试剂盒(胶体金法)英文名称:Strep A Test【包装规格】25人份/盒。
【预期用途】A群链球菌抗原检测试剂盒(胶体金法)是一种快速免疫层析试验,用于定性检测咽拭子标本中的A群化脓性链球菌抗原。
A群链球菌是引起咽炎的主要病原体。
对该致病原做出准确诊断是正确治疗这种疾病的重要条件。
链球菌感染后要选用抗生素治疗,如果未经治疗,可能会引起诸如风湿热之类的严重后遗症1。
检测A群链球菌感染的传统方法是将咽拭子标本培养24-48小时后,证实β溶血菌落是A群链球菌2。
阳性结果可通过观察羊血琼脂平板上微生物对杆菌肽的敏感性而获得3,4。
基于碳水化合物抗原群特异性可对A群链球菌做出免疫学诊断5。
A群链球菌抗原检测试剂盒(胶体金法)使用的是免疫层析方法,所用抗体对A群链球菌是特异的。
试验设计可对抗原在试剂上进行提取,没有转移步骤,标本完全包含在检测卡中,结果6分钟可得。
【检验原理】A群链球菌抗原检测试剂盒(胶体金法)是一种检测咽拭子标本中A群化脓性链球菌抗原的薄膜免疫层析试验。
一条吸附到硝酸纤维素膜上的兔抗A群链球菌抗体带,作为样本线,另一条吸附到同一膜上的兔抗种属抗体,作为对照线。
结合有可视粒子的兔抗A群链球菌抗体和种属抗体干燥结合到惰性纤维支持物上,形成的结合物垫与带条带的薄膜结合在一起构成检测条。
检测条和一个放咽拭子的小孔位于书形检测卡的两侧。
试验时,将咽拭子插入检测卡中,从滴瓶中加入提取试剂,将咽拭子转三圈。
温育1分钟后,将检测卡闭合,使提取的标本与检测条接触。
A群链球菌抗原被固定的A群链球菌抗体捕获,并与结合物抗体结合。
固定的抗种属抗体捕获另一可视结合物,阳性结果5分钟内出现,5分钟读数时的阴性结果表明不存在A群链球菌抗原。
试验结果可用紫红色线的存在与否来解释。
阳性结果会出现样本线和对照线两条线,阴性结果只出现一条对照线,其他检测结果表示试验无效。
注射用阿替普酶使用说明书(德国进口)
注射用阿替普酶使用说明书(德国进口)之答禄夫天创作中文名:注射用阿替普酶商品名:爱通立曾用名:艾通立英文名:Actilyse化学名称:Plasminogen activator (human tissue-type protein moiety)分子式:CHNOPS分子量:C2569H3894N746O781S40活性成分:阿替普酶 Alteplase (重组人组织纤维卵白溶酶原激活剂 (rt-PA))性状:本品为白色至类白色冻干粉末, 无嗅.除活性成分外, 还含有以下辅料:精氨酸、磷酸、吐温80及注射用水.20毫克包装盒内有一个含20毫克活性成分(干粉总重933毫克)的小瓶及一个内装20毫升注射用水的注射用小瓶.50毫克包装盒内有一个含50毫克活性成分(干粉总重2333毫克)的小瓶及一个内装50毫升注射用水的注射用小瓶.作用机理:本药的活性成分是一种糖卵白, 可直接激活纤溶酶原转化为纤溶酶.当静脉给予时, 本品在循环系统中暗示出相对非活跃状态, 一旦与其纤维卵白结合后, 本品被激活, 诱导纤溶酶原转化为纤溶酶, 招致纤维卵白降解, 血块溶解.心肌梗死的研究:在一项入选了40000多例急性心肌梗死患者的研究(GUSTO)中, 治疗组给予100毫克本品90分钟滴注, 静脉滴注肝素辅助治疗, 30天死亡率为6.3% ;对比组予以150万单元链激酶60分钟滴注, 辅以皮下或静滴肝素比较, 其30天死亡率为7.3%.同时本品治疗的患者溶栓后60分钟和90分钟的血管再通率高于链激酶治疗的患者.在180分钟及以后时间的血管再通率2组没有不同.本品治疗的患者比未经溶栓治疗的患者30天死亡率低.与未经溶栓疗法的患者相比, 本品治疗的患者总体心室功能及局部心肌壁运动功能受损较轻.一项抚慰剂对比试验(LATE)标明, 发病后6-12小时内给予治疗, 经本品100 mg 3小时治疗的患者30天死亡率比对比组低.对某些呈现明显心肌梗死症状的病例, 发病后24小时内的溶栓治疗也有益处.肺栓塞的研究:急性年夜面积肺栓塞伴血流动力学不稳定的患者使用本品溶栓, 可迅速缩小血栓, 并降低肺动脉压.无死亡率的资料.急性缺血性脑卒中的研究:在2项美国试验(NINDS A/B)中, 与抚慰剂相比, 使用本品预后良好(无功能缺陷或轻微功能缺陷)的患者比例明显增高.在2个欧洲试验和另外1个美国试验中未能证实上述发现, 然而在这后3个试验中, 年夜部份患者未能在脑卒中发作的3小时内接受治疗.随后的分析标明在脑卒中发作3小时内接受本品治疗的疗效是肯定的.尽管严重的和致命性的颅内出血的风险增高, 但与抚慰剂相比, 预后良好的差值为14.9%(95%可信区间为8.1-21.7%).此数据无法给出关于治疗对死亡率影响简直切结论.然而总体来说, 如果在卒中症状发作的3小时内给予本品且遵循本说明书描述的各注意事项, 应用本品的收益还是年夜于可能的风险的.随后进行的对所有临床数据的分析显示, 与症状发作3小时内就给予本品治疗的患者相比, 在症状发作3小时后(3-6小时)才接受本品治疗的患者疗效差, 而且风险增高, 这招致其收益/风险比值落在原来0-3小时内可接受的值以外.由于本品具有纤维卵白相对特异性, 100毫克的本品可能招致循环中纤维卵白原在4小时内减少至60%左右, 但一般24小时后可恢复到80%以上.4小时后纤溶酶原和α-2-抗纤溶酶分别减少至20%和35%左右, 24小时后可恢复到80%以上.只有少数患者呈现明显的较长时间的循环纤维卵白原水平下降.毒理研究:在年夜鼠和南美猴的亚急性毒理研究中, 未发现其它预期之外的不良反应.致突变试验中未发现有致突变倾向.药代动力学:本品可从血循环中迅速清除, 主要经肝脏代谢(血浆清除率550-680毫升/分钟).相对血浆α半衰期(T1/2α)是4~5分钟, 这意味着20分钟后, 血浆中本品的含量不到最初值的10%.周边室的残留量, 其β半衰期为40分钟.适应症:急性心梗、血流不稳定的急性年夜面积肺栓塞、急性缺血性脑卒中的溶栓治疗.急性心肌梗死:对症状发生6小时以内的患者, 采用90分钟加速给药法(拜会用法用量);对症状发生6-12小时以内的患者, 采用3小时给药法(拜会用法用量).本品已被证实可降低急性心肌梗死患者30天死亡率.血流不稳定的急性年夜面积肺栓塞:可能的情况下应借助客观手段明确诊断, 如肺血管造影或非侵入性手段如肺扫描等.尚无证据显示对与肺栓塞相关的死亡率和晚期发病率有积极作用.急性缺血性脑卒中:必需预先经过恰当的影像学检查排除颅内出血之后, 在急性缺血性脑卒中症状发作后的3小时内进行治疗.用法用量:心梗发病6 hr内:采用90分钟加速给药法.静推15 mg, 其后30分钟内静滴50 mg, 剩余的35 mg在60分钟内静滴, 直至最年夜剂量达100 mg.心梗发病6-12 hr :采用3小时给药法.静推10 mg, 其后1 hr内静滴50 mg, 剩余的按10 mg/30分钟, 至3小时末静滴完毕, 直至最年夜剂量达100 mg.体重< 65 kg患者, 给药总剂量不应超越1.5 mg/kg.肺栓塞:应在2 hr内给予100 mg, 10 mg 在1-2分钟内静推, 90 mg在2 hr内静滴.急性缺血性脑卒中:在卒中症状发作后的3 hr内尽快给予0.9 mg/kg, 最年夜剂量为90 mg.先将剂量的10%静脉推入, 剩余剂量在1 hr内静滴.(详见说明书)应在症状发生后尽快按以下指导剂量给药.无菌条件下將一小瓶爱通立干粉(10、20或50毫克)用注射用水溶解为1毫克/毫升或2毫克/毫升的浓度.使用爱通立20毫克或50毫克包装中的移液套管完成上述溶解把持.如果是爱通立10毫克, 则使用注射器.10 毫克规格:加入干粉中注射用水10毫升, 终浓度为1毫克/毫升;加入干粉中注射用水5毫升, 终浓度为2毫克/毫升.20 毫克规格:加入干粉中注射用水20毫升, 终浓度为1毫克/毫升;加入干粉中注射用水10毫升, 终浓度为2毫克/毫升.50 毫克规格:加入干粉中注射用水50毫升, 终浓度为1毫克/毫升;加入干粉中注射用水25毫升, 终浓度为2毫克/毫升.配制好的溶液应通过静脉给药.配制的溶液可用灭菌生理盐水(0.9%)进一步稀释至0.2毫克/毫升的最小浓度.心肌梗死:对在症状发生6小时以内的患者, 采用90分钟加速给药法:15 mg静脉推注, 终浓度为1毫克/毫升的溶液15毫升, 或终浓度为2毫克/毫升的溶液7.5毫升.随后30分钟继续静脉滴注50 mg, 终浓度为1毫克/毫升的溶液50毫升, 或终浓度为2毫克/毫升的溶液25毫升.剩余35 mg于60分钟继续静脉滴注, 终浓度为1毫克/毫升的溶液35毫升, 或终浓度为2毫克/毫升的溶液17.5毫升.直至最年夜剂量达100 mg.体重在65公斤以下的患者, 给药总剂量应按体重调整, 具体如下:15 mg静脉推注, 终浓度为1毫克/毫升的溶液15毫升, 或终浓度为2毫克/毫升的溶液7.5毫升.然后按0.75毫克/公斤体重的剂量继续静脉滴注30分钟(最年夜剂量50毫克), 终浓度为1毫克/毫升的溶液0.75毫克/公斤体重, 或终浓度为2毫克/毫升的溶液0.375毫克/公斤体重.剩余的按0.5毫克公斤/体重的剂量继续静脉滴注60分钟(最年夜剂量35毫克), 终浓度为1毫克/毫升的溶液0.5毫克/公斤体重, 或终浓度为2毫克/毫升的溶液0.25毫克/公斤体重.对在症状发生6-12小时以内的患者, 采用3小时给药法:10 mg静脉推注, 终浓度为1毫克/毫升的溶液10毫升, 或终浓度为2毫克/毫升的溶液5毫升.其后1小时继续静脉滴注50 mg, 终浓度为1毫克/毫升的溶液50毫升, 或终浓度为2毫克/毫升的溶液25毫升.剩余剂量每30分钟静脉滴注10毫克, 终浓度为1毫克/毫升的溶液10毫升/30分钟, 或终浓度为2毫克/毫升的溶液5毫升/30分钟.至3小时末滴完, 最年夜剂量为100 mg.体重在65公斤以下患者, 给药总剂量不应超越 1.5 mg/kg体重.本品最年夜剂量为100毫克.辅助治疗:症状发生后尽快给予阿司匹林, 并在心肌梗死发生后的第1个月内继续给药.推荐剂量为160 -

State Key Laboratory of Nature Medicines, China Pharmaceutical University, Nanjing 210009, China2. Institute of Vaccine Research, Jiangsu Simcere Pharmaceutical Group, Nanjing 210042, ChinaDespite the long availability of a traditional prophylactic vaccine containing the HBV surface antigen (HBsAg) and aluminum adjuvant, nearly 10% of the population remains unable to generate an effective immune response. Previous studies have indicated that hepatitis B virus (HBV) PreS2-S is abundant in T/B cell epitopes, which induces a stronger immune response than HBsAg, particularly in terms of cytotoxic T lymphocyte (CTL) reaction. In the current study, the HBV PreS2-S gene encoding an extra 26 amino acids (PreS2 C-terminus) located at the N-terminus of HBsAg was cloned into the pVCH1300 expression vector. PreS2-S expressed in the methylotrophic yeast, Hansenula polymorpha , was produced at a yield of up to 250 mg/L. Subsequent puri fi cation steps involved hydrophobic adsorption to colloidal silica, ion-exchange chromatography and density ultracentrifugation. The fi nal product was obtained with a total yield of ~15% and purity of ~99%. In keeping with previous studies, ~22 nm virus-like particles were detected using electron microscopy. The generated PreS2-S antigen will be further studied for ef fi cacy and safty in animals. KEYWORDS hepatitis B virus (HBV); PreS2-S; virus-like particle (VLP); Hansenula polymorphaReceived: 27 September 2014, Accepted: 15 December 2014Published online: 24 December 2014✉ Correspondence:Jianqiang Li: Phone: +86-25-85560000 (Ext: 3052), Email:************************Hanmei Xu: Phone: +86-25-86185437,Email:139****************VIROLOGICA SINICA 2014, 29 (6): 403-409DOI 10.1007/s12250-014-3508-9I NTRODUCTION Hepatitis B virus belongs to hepadnaviridae , a family of enveloped viruses containing a partially double-stranded and circular DNA genome (G. Birkenmeyer L, 2003). Records show that more than 350 million people world-wide are infected by this virus (Awan A R, et al., 2012). Clinical antiviral therapies currently used for chronic hepatitis B infection often lead to drug tolerance and are unable to eradicate the virus completely (Janssen H L, et al., 2005; Liaw Y F, et al., 2000; Niederau C, et al., 1996). Although an effective prophylactic vaccine has been available for nearly 30 years to date, up to 10%of individuals do not experience a response with anadequate antibody level to hepatitis B surface antigen (Sjogren M H, 2005). Therefore, development of a novel hepatitis B vaccine with a better penetrating and a higher response rate is essential.The HBV envelope consists of three major immuno-genic proteins, known as large (PreS1-PreS2-S), medium (PreS2-S) and small protein (HBsAg), and is the main component of the currently licensed recombinant prophy-lactic vaccine (Hadiji-Abbes N, et al., 2009). Previous studies have suggested that the PreS2-S region has the strongest immunogenicity, which could enhance anti-body response to HBsAg and thus mitigate the chance of non-responsiveness of vaccines against escape variants, making it the most suitable candidate antigen for a novel HBV vaccine (Hadiji-Abbes N, et al., 2009). However, the entire PreS2 region containing 55 amino acids is sen-sitive to protease degradation, which makes large-scale preparation difficult (Langley K E, et al., 1988). The C-terminus of PreS2 containing 26 amino acids (120-145 aa) has been shown to be the most effective immu-Hepatitis B Virus PreS2-S VLP generationVIROLOGICA SINICA404 D ECEMBER 2014 V OLUME 29 I SSUE6nogen for production of antisera and has been proposed to contain a conserved conformational epitope critical for neutralization of infection (Chi S W, et al., 2006). Moreover, PreS2 containing 26 amino acids (120-145 aa) appears more stable than PreS2 containing 55 amino acids. Therefore, a truncated PreS2-S protein comprising 120-145 aa of the PreS2 (26 aa) C-terminus and entire HBsAg was used in the current study.The methylotrophic yeast Hansenula polymorpha (H. polymorpha ), a highly ef fi cient microbial cell factory, has been successfully used in the production of several cur-rent commercial prophylactic HBV vaccines (Gellissen G, et al., 1992; Huang Y, et al., 2007). Here, H. poly-morpha was employed as the host strain to express HBV PresS2-S, leading to a production yield of up to 250 mg per liter. After several steps of puri fi cation, total yield of ~15% with ~99% purity was obtained. Consistent with previous findings, ~22 nm virus-like particles were de-tected using electron microscopy. MATERIALS AND METHODSStrains and reagentsH. polymorpha DL-1 (ATCC 26012) was purchased from ATCC, Geneticin TM (G418) from Invitrogen (Life Technologies, California, USA), the PCR cloning kit from Toyobo (Toyobo, Osaka, Japan) and CsCl from Sigma Aldrich (Sigma Aldrich, Missouri, USA). Eco R I , Not I , Bgl II were purchased from Takara (Takara Bio Inc., Otsu, Japan).Plasmid construction and protein expression The codon-optimized coding sequence of adw2-sub-type HBV PreS2-S antigen (containing 26 aa of PreS2 C-terminus) was amplified from pVAC1010-PreS2-S (plasmid stored in our laboratory). Briefly, the PreS2-S was amplified by KOD plus kit according to the manufacturer’s instructions using primer M26-F: CCGGAATTCGACATGGGTACAGTTAGTC (Eco R I) and primer M-R: ATAGTTTAGCGGCCGCTTAAATGT (Not I). The ampli fi ed coding sequence was subsequent-ly digested with Eco R I, Not I and inserted into the expression vector, pVCH1300. The resultant plasmid was sequenced by GENEWIZ, Inc (Suzhou, China). For yeast transformation, plasmid pV CH1300-PreS2-S was linearized with the restriction endonuclease Bgl II and transformed into H. polymorpha according to the method described by Faber et al. (1994). Positive clones were cultured in BMGY or YPD medium at 220 rpm/min, 37ºC, for 1 day and induced using 1% (w/v) methanol f o r 48 h. Protein puri fi cationHarvested cells was re-suspended in sodium phos-phate buffer (50 mmol/L PB, 150 mmol/L NaCl, pH8.0) and disrupted with a high-pressure homogenizer at 4 ºC (1500 bar, 4 ). The cell debris was removed via centrifugation at 4 ºC, 4,400 g , for 15 min and the super-natant mixed with colloidal silica Aerosil-380 (Evonik Degussa, Essen, Germany ), which was pre-equilibrated in 25 mmol/L sodium phosphate buffer, 0.5 mol/L NaCl, pH 7.2. The suspension was stirred at 4 ºC for 4 h and centrifuged at 4 ºC, 7500 g , for 30 min. The pellet was washed with 25 mmol/L sodium phosphate buffer, pH 7.2, and centrifuged as above. The resultant pellet was re-suspended in 100 mmol/L sodium carbonate-bicarbon-ate buffer (pH 10.8) and incubated at 37 ºC for 4 h. The suspension was centrifuged at 25 ºC, 10,000 rpm, for 1 h. The clari fi ed supernatant was adjusted to pH 8.0 and processed using ion-exchange chromatography (DEAE Sepharose FF, GE Healthcare). Bound PreS2-S was eluted using a salt step (50 mmol/L Tris-HCl buffer, pH 8.0, 0-1 mol/L NaCl). PreS2-S-containing fractions were pooled and further separated via CsCl density gradient centrifu-gation (Beckman, California, USA) at 36,000 rpm and 4 ºC for 16 h.Quantitative measurement of PreS2-S using ELISAThe PreS2-S concentration in the crude extract was determined using a commercially available ELISA kit (Kehua Bio-engineering, Shanghai, China). Purified PreS2-S was employed to establish a standard curve. Crude yeast extract containing PreS2-S was diluted appropriately with 0.1% BSA in PBS (pH 7.2) and ap-plied for ELISA. The resultant absorption values were converted to PreS2-S concentrations using the standard curve established above. All samples were analyzed in triplicate.Silver staining and Western BlotThe protein sample was separated using 12% SDS-PAGE and characterized via silver staining acc ording to the manual of Novex (Life Technologies, California, USA). Western blot analysis was carried out us-ing mouse anti-human HBsAg polyclonal antibody (ABMAX, Beijing, China) and HRP-conjugated goat anti-Mice IgG antibodies (Sigma Aldrich, Missouri,USA ). Brie fly, NC membrane was incubated with pri-mary antibody (1:1000 dilution) in 5% blocking solu-tion at 37°C for 40 min. After washing with TBST, the membrane was incubated with HRP-conjugated second-ary antibody (1:10000 dilution) in 5% blocking buffer at 37°C for 30 min. Signal detection was performed using Western Lightning® Plus-ECL (PerkinElmer. Inc, Massachusetts, USA )Electron Microscopy T h e structure of PreS2-S virus-like particles was con-Xiaowei Xu et al D ECEMBER 2014 V OLUME 29 I SSUE 6 405fi rmed using transmission electron microscopy (HT7700, Hitachi). Purified samples were applied to a 400-mesh copper grid, dried, and stained with 2% tungstophosphor-ic acid before TEM observation. The particle size was measured using Image J software.RESULTSPlasmid constructionThe coding sequence of the adw2-subtype HBV PreS2-S antigen (containing 26 amino acids of the PreS2 C-terminus, 120-145 aa) was optimized according to the codon bias of H. polymorpha (Figure 1A ). The op-timized sequence was ampli fi ed and further cloned into the expression vector, pVCH1300, under the control of the strong methanol-inducing MOX promoter (Figure 1B and 1C ). A geneticin (G418) resistance gene was used as a positive selection marker. The resultant plasmid was veri fi ed using colony PCR and restriction enzyme ana l y-sis (Figure 1D ).Expression of PreS2-SThe plasmid was transformed into H. polymorpha cells using a previously published method (Faber K N, et al.,1994). Multiple copy inserts were screened according to protocols of the Invitrogen manual and further con fi rmed using rea1-time PCR (data not shown). The resultant multiple copy colonies were cultured in YPD medium and induced with methanol at a fi nal concentration of 1% (Figure 2A and 2B ). Induced samples were collected at the indicated time-points and characterized using Western blot (Figure 2C ). After two days of methanol induction, the expression yield was estimated as 250 mg/L culture (2.5 mg/g wet cells).Puri fi cation of HBV PreS2-SHarvested cells was re-suspended in sodium phosphate buffer and disrupted using a high-pressure homogenizer. After clarification via centrifugation at 4,400 g for 15 min, the supernatant containing HBsAg was further clari-fi ed with colloidal silica. The salt steps in the puri fi cation of PreS2-S protein using DEAE Sepharose FF chroma-tography are presented in Figure 3A . The SDS-PAGE pattern (Figure 3B ) showed that the fraction eluted with buffer (50 mmol/L Tris-HCl pH 8.0 plus 500 mmol/L NaCl) mainly contained the monomer and polymer forms of the desired protein and no other evident bands of host protein. PreS2-S-containing fractions were pooled, fur-Figure 1. A: Schematic representation of the truncated PreS2-S.

We observed enrichment of PreS2-S mainly in fractions 7-8 (~1.18 g/mL) (Figure 3C ). The final product, with a total yield of ~15% and purity of 99%, was quanti fi ed using ELISA, as described above.Electron Microscopy fi ndingsHBsAg needs to assemble into spherical particles, so-called virus-like particles (VLPs), to initiate the re-quired protective immune response (Cabral G A, et al., 1978). To establish whether PreS2 is able to assemble into VLPs, transmission electron microscopy was per-formed. The hepatitis B PreS2-S antigen derived from H. polymorpha cells organized into 22.6±3.0 (n =32) nm virus-like particles (Figure 4A and 4B ), which were morphologically similar to those isolated from S a ccharomyces cerevisiae and Pichia pastoris . DISCUSSIONHepatitis B virus (HBV) infection is the main cause ofcirrhosis and hepatocellular cancer (Torbenson M, et al., 2002). The currently available recombinant prophylactic vaccine for HBV, either expressed in Chinese hamster ovary (CHO) cells or yeast, can induce effective humoral responses (Chen H, et al., 2012). However, up to 10% of individuals are still unable to experience a response with an adequate protective antibody level to hepatitis B surface antigen (Sjogren M H, 2005). Therefore, there remains an urgent requirement for a novel hepatitis B vaccine with a better penetrating and response rate.The HBV envelope consists of three major immuno-genic proteins, known as large (PreS1-PreS2-S), medi-um (PreS2-S) and small protein (HBsAg), respectively. The PreS2-S region has the strongest immunogenicity, which could accelerate antibody response to HBsAg and thus lower the chance of non-responsiveness of vaccines against escape variants (Hadiji-Abbes N, et al., 2009). Moreover, the PreS2 region contains a conserved polym-erized albumin receptor site involved in virus attachment to human hepatocytes, and anti-PreS2 antibodies often arise earlier than anti-HBsAg antibodies (Kuroda S, et al., 1991; Milich D R, et al., 1985).Figure 2. pVCH1300-PreS2-S transformed H. polymorpha cells growth curves before (A) and after methanolinduction (B). Samples inducing at indicated time points were characterized by Western-Blot (C).Xiaowei Xu et alFigure 3. Purification of HBVPreS2-S from H. polymorphacells.

Therefore, a truncated PreS2-S protein compris-ing the C-terminus of PreS2 (120-145 amino acids, 26 aa) and entire HBsAg was used in this study. Vaccines containing PreS2 can compete with HBV and block the route of infection, implying that PreS2 is a potential can-didate component of novel HBV vaccines (Jiang Z G, et al., 2007).The methylotrophic yeast, H. polymorpha , is a highly ef fi cient microbial cell factory (Gellissen G, et al., 1992). Here, a PreS2(26 aa)-S truncated gene was cloned into pVCH1300 and transformed into H. polymorpha DL-1. High dose G418-resistant colonies were screened and confirmed via real-time quantitative PCR. Remarkably, nearly 60 copies of plasmid were integrated into the ge-nome of H. polymorpha DL-1 cells and transferred stably in progeny (data not shown), which possibly contributed to the significant production of foreign proteins. In our experiments, PreS2-S production yield in H. polymorpha cells was up to 250 mg per liter. Additionally, the gen-eration process was more productive and cost-effective. After several steps of puri fi cation, a total yield of ~15% with ~99% purity was obtained, which was significantly higher than that from Pichia pastoris (Hardy E, et al., 2000). As a prerequisite for initiating the protective immune response, the ability to assemble into ~22 nm virus-like particles of PreS2-S antigen derived from H. polymorpha cells was con fi rmed using electron micros-copy (Cabral G A, et al., 1978). To our knowledge, this is the fi rst report of intracellular expression of PreS2-S VLPs in H. polymorpha. Further animal immunization studies with this antigen are required to fully evaluate PreS2-S as a potential vaccine candidate. Efficacy and safety studies will be reported in future publications.ACKNOWLEDGMENTSWe are grateful to our colleagues for sharing their re-sults during scienti fi c meetings and informal discussions.

普腾免疫试剂二抗应用说明书
IntroductionApplications ForSecondary AntibodiesIn many biological assays, the target antigen is visualizedindirectly. That is, the secondary antibody, bound to the primary antibody, produces the signal. Since many secondary antibodies can bind to one primary antibody, the result is signal amplification and increased sensitivity.The choice of the appropriate secondary antibody is determined by the specifications (i.e. species, subclass, and fragment type) of the primary antibody and the application. Proteintech ®* offers a variety of secondary antibodies suitable for Western Blotting, ELISA, cellular imaging, and flow cytometry: –Enzyme/Biotin conjugated–Conventional fluorescent conjugatedWestern Blotting ELISAImmunofluorescence Staining ImmunohistochemistryFlow CytometrySECONDARY ANTIBODIES*Proteintech and the Proteintech logo are trademarks of Proteintech Group registered in the US Patent and Trademark Office.Secondary AntibodiesSelecting A SuitableSecondary AntibodyFor Your ApplicationUnderstanding Common Secondary Antibody Nomenclature 1. Host Species Of Primary AntibodyThe secondary antibody has to be raised against the host species of the primary antibody (e.g., anti-mouse, rabbit, rat).2. Class Of Primary AntibodyIn addition to the host specificity, the secondary antibody also has to be specific for the isotype of the primary antibody (e.g., IgG, IgA, IgM).4. Assay RelevanceThe intended application determines the type of conjugate (eg., enzyme orfluorescent conjugated).5. Additional Purification StepsA common purification technique for secondary antibodies is High Affinity Purification, resulting in reduced non-specific binding. In addition, secondary antibodies can go through an additional purification step to reduce potential cross-reactions with other species. Therefore, the secondary antibody solution is passed over different columns containing sera proteins of different species to filter out the non-specific secondary antibody (e.g., for multi-stainings).3. Antibody FragmentsIf the primary antibody is not thewhole antibody but a fragment,the secondary antibody shouldalso be fragment-specific to reducenoise signal (e.g., F(ab’)₂ fragmentsecondary antibodies penetratetissue easier in IHC).Ms Mouse Gt Goat rRb Rabbit Sh SheepRt Rat BV Bovine Hn Human Sw SwineIgG (H+L), heavy and light chain IgG3IgG1 IgG, Fc, receptor bindingIgG2a IgAIgG2bIgMUnderstanding the needs of the primary antibody and assay-dependent requirements are essential for selecting an appropriatesecondary antibody.2Seconday Antibodies3 Enzyme Conjugated/ Biotin Secondary AntibodiesConventional Fluorescent ConjugatedSecondary AntibodiesOPTIMIZE YOUR ANTIBODY EXPERIMENTS WITH PROTEINTECHRequest your free technical guide from .LIVE CHAT TWITTER@proteintechBLOG/news/blog YOUTUBE/ProteintechSupportAvailable 24 hours via Live Chat and 9-5 (CDT) via phone.Email support also available.1 (888) 4PTGLAB (1-888-478-4522) (toll free in USA),or 1(312) 455-8498 (outside USA)1 (312) 455-8408Proteintech Group, Inc.5400 Pearl Street, Suite 300, Rosemont, IL 60018, USA **********************PHONEFAX ADDRESSEMAILPHONE EMAIL FAX ADDRESSEMAIL+44 (161) 8393007+44 (161) 2413103Proteintech Europe, Ltd. 4th Floor,196 Deansgate, Manchester, M3 3WF ***********************************Sales and technical support only.PHONE FAX ADDRESSEMAIL************or 4006-900-926************Wuhan Sanying Biotechnologies D3-3, No.666 Gaoxin Avenue,Wuhan East Lake Hi-tech Development Zone Wuhan, Hubei, P .R.C******************We are ISO 9001 and ISO 13485 accredited.Proteintech GroupUS Head OfficeProteintech EuropeUnited KingdomProteintech EuropeGermanyProteintechChina OfficeCONTACT US。
