INTRODUCTIONThe RayBio® Mouse Insulin ELISA kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Mouse Insulin in serum, plasma (Collect plasma using EDTA and Citrate as an anticoagulant. Heparin is not recommended as anticoagulants for use in this assay) and cell culture supernatants. This assay employs an antibody specific for Insulin coated on a 96-well plate. Standards and samples are pipetted into the wells and Insulin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Mouse Insulin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Insulin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.Need your results faster? Try RayBiotech's SpeedE LISA platform for quantitative detection in just three hours.https:///speedelisa-kits/Short on sample, or need higher sensitivity? Check out the IQELISA™ Immuno-PCR platform. https:///immuno-pcr/II. STORAGEThe entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C. For prepared reagent storage, see table below. III. REAGENTSIV.

REAGENT PREPARATION1.Bring all reagents and samples to room temperature (18 - 25ºC) before use.2.Assay Diluent B (Item E) should be diluted 5-fold with deionized or distilled water before use.3.Sample dilution: Assay Diluent C (Item L) should be used for dilution of serum, plasma, and cell culture supernatant samples. The suggested dilution for normal serum/plasma is 2 fold. Collect plasma using EDTA and/or Citrate as anticoagulants. Heparin is not recommended as an anticoagulant for use in this assay. Note: Levels of Insulin may vary between different samples. Optimal dilution factors for each sample must be determined by the investigator.4.Preparation of standard: Briefly spin a vial of Item C. Add 400 µl Assay Diluent C (Item L) into Item C vial to prepare a 1,400 µIU/ml standard solution. Dissolve the powder thoroughly by a gentle mix. Add 180 µl Insulin standard (1,400 µIU/ml) from the vial of Item C, into a tube with 450 µl Assay Diluent C to prepare a 400 µIU/ml standard solution. Pipette 250µl Assay Diluent C into each tube. Use the 400 µIU/ml standard solution to produce a dilution series (shown below). Mix each tube thoroughly before the next transfer. Assay Diluent C serves as the zero standard (0 µIU/ml).180 µl250 µl 250 µl 250 µl 250 µl 250 µl250 µlStd1Std2Std3Std4Std5Std6Std7Zero Standard Diluent volume Item C + 400 µl450 µl250 µl250 µl250 µl250 µl250 µl250 µl250 µlConc.1,400 µIU/ml 400 µIU/ml 200 µIU/ml 100 µIU/ml 50 µIU/ml 25 µIU/ml 12.5 µIU/ml 6.25 µIU/ml0 µIU/ml5.If the Wash Concentrate (20X) (Item B) contains visible crystals, warm to roomtemperature and mix gently until dissolved.

胰岛素简介:胰岛素是糖代谢中最主要的激素之一。

胰腺的ß细胞岛细胞产生胰岛素前体蛋白,前体蛋白被加工成C肽和胰岛素。

它们以等摩尔浓度进入血循环中。

成熟的胰岛素由A、B两条链组成。

这两条链是通过两个二硫键桥接形成有功能的胰岛素分子。

血浆葡萄糖浓度的变化是胰岛素产生并分泌的最主要刺激因素,产生的胰岛素具有一些代谢调节作用。

其最主要的作用是,将外周血中糖转运到肝脏中贮存起来。

一些诸如肝糖生成障碍或在促进血糖升高的激素诸如胰高血糖素、肾上腺素、生长激素和皮质醇等作用下促进肝糖分解都可拮抗胰岛素的作用。

检测原理:本试剂盒采用双抗体夹心ELISA法检测样本中胰岛素的浓度。

胰岛素捕获抗体已预包被于酶标板上,当加入标本或参考品时,其中的胰岛素会与捕获抗体结合,其它游离的成分通过洗涤的过程被除去。

当加入与HRP耦连的抗胰岛素抗体后,抗小鼠胰岛素抗体与胰岛素接合,形成夹心的免疫复合物,其它游离的成分通过洗涤的过程被除去。

最后加入显色剂,若样本中存在胰岛素将会形成免疫复合物,辣根过氧化物酶会催化无色的显色剂氧化成蓝色物质,在加入终止液后呈黄色。

通过酶标仪检测,读其450nm处的OD值,胰岛素浓度与OD450值之间呈正比,通过参考品绘制标准曲线,对照未知样本中OD值,即可算出标本中胰岛素浓度。

2.血清标本不应添加任何防腐剂或抗凝剂;3.标本应清澈透明,检测前样本中如有悬浮物应通过离心去除。

4.请勿使用溶血,高血脂或污染的标本检测,否则结果将不准确。

注意事项:1.试剂盒请保存在2~8℃。

2.浓缩洗涤液因在低温下可能有结晶,请水浴加热使结晶完全溶解后再配制工作液。

3.标准品复溶加样后,剩余部分请丢弃。

4.底物请勿接触氧化剂和金属。

5.加样时,请及时更换枪头,避免交叉污染。

6.严禁混用不同批号的试剂盒组份。

7.充分混匀对保证反应结果的准性很重要,在加液后请轻轻叩击边缘以保证混匀。

8.室温反应,请严格控制在25~28℃。

9.洗涤过程是至关重要的,洗涤不充分会使精确度下降并导致结果误差较大。

10.试验中标准品和样本检测时建议作双复孔。

11.加样过程中避免气泡的产生。

12.血清和血浆标本的检测时,检测抗体的孵育时间应适当延长。

检测前准备工作:1.试剂盒自冰箱中取出后应置室温(25~28℃)平衡20分钟;每次检测后剩余试剂请及时于2~8℃保存。

2.将浓缩洗涤液用双蒸水或去离子水稀释(1份加19份水)。

3.标准品:加入标准品稀释液1.25ml至冻干标准品瓶中使胰岛素终浓度达到5.5ng/ml,室温反应,请严格控制在25~28℃,静置10~15分钟后轻轻混悬(建议抽吸几次)待彻底溶解,用标准品稀释液倍比梯度稀释后依次加入检测孔中。

(标准曲线取七个点,最高浓度为5.5ng/ml,标准品稀释液直接加入作为0浓度.)洗涤方法:自动洗板机或人工洗板:每孔洗涤液为300ul,注入与吸出间隔15-30秒。

洗板5次。

最后一次洗板完成后将板倒扣着在厚吸水纸上用力拍干。

实验过程需自备的材料:1.不同规格的加样枪及相应的枪头;2.酶标仪;3.自动洗板机;4.去离子水或双蒸水;操作步骤:1.通过计算并确定一次性实验所需的板条数,取出所需板条放置在框架内,暂时用不到板条请放回铝箔袋密封,保存于4℃。

2.建议设置本底较正孔,即空白孔,设置方法为该孔只加TMB显色液和中止液。

每次实验均需做标准品对照并画出标准曲线。

3.分别将标本或不同浓度标准品(10ul/孔)加入相应孔中,快速加入小鼠胰岛素抗体HRP结合物(100ul/孔)。

用封板胶纸封住反应孔,室温(25~28℃)孵育120分钟。

4.洗板5次,且最后一次置厚吸水纸上拍干。

5.加入显色剂TMB100ul/孔,避光室温(25~28℃)孵育10分钟。

6.加入终止液50ul/孔,混匀后即刻测量OD450值。

结果判断:1.复孔的值在20%的差异范围内结果才有效,复孔的值平均后可作为测量值。

2.每个标准品或标本的OD值应减去本底校正孔的OD值。

3.手工绘制标准曲线。

以标准品浓度作横坐标,OD值作纵坐标,以平滑线连接各标准品的坐标点。

通过标本的OD值可在标准曲线上查出其浓度。

4.若标本OD值高于标准曲线上限,应适当稀释后重测,计算浓度时应乘以稀释倍数。

Please read this instruction manual carefully and check out the material provided before use, and you can contact with our company if any questions.

It is synthesized in the ß-cells of the islets of Langerhans as the precursor, proinsulin, which is processed to form C-peptide and insulin. Both are secreted in equimolar amounts into the portal circulation. The mature insulin molecule comprises two polypeptide chains, the A chain and B chain (21 and 30 amino acids respectively). The two chains are linked together by two inter-chain disulphide bridges.Secretion of insulin is mainly controlled by plasma glucose concentration, and the hormone has a number of important metabolic actions.Its principal function is to control the uptake and utilisation of glucose in peripheral tissues via the glucose transporter. This and other hypoglycaemic activities, such as the inhibition of hepatic gluconeogenesis and glycogenolysis are counteracted by the hyperglycaemic hormones including glucagon, epinephrine (adrenaline), growth hormone and cortisol.Principles of the TestThe kits is a solid sandwich enzyme-linked immunosorbent assay for detection of mouse Insulin. An anti- mouseInsulin monoclonal antibody has been absorbed onto the wells of the microtiter strips provided. Samples including specimens or standards were pipetted into wells. The mouseInsulin in specimens or standards would be captured by the coated antibody and the free others were removed by washing. The mouse Insulin HRP-conjugated antibody were added and binds to mouse Insulin captured by the first antibody, which formed a sandwich. After this, subtrate solution would be added and catalyzed by the HRP, and a coloured product is formed. The intensity of the colored product is used to calculate in proportion to the amount of mouse Insulin in the original specimen.
