考马斯亮蓝染色

考马斯亮蓝染色一产品简介:本考马斯亮蓝染色试剂盒(Commassie Blue Staining Kit)采用了最经典的考马斯亮蓝染色和脱色方法,以考马斯亮蓝R250为染料,可用于SDS-PAGE或非变性PAGE等蛋白电泳凝胶的常规染色和脱色,或Western转膜后PAGE胶上残余蛋白的检测。
使用本试剂盒,采用常规染色脱色方法累计时间达到2-3小时后可以观察到蛋白条带;采用快速染色脱色方法20分钟左右即可观察到蛋白条带。
观察到最清晰的蛋白条带则需染色脱色更长时间。
本试剂盒中的染色液和脱色液经过改良,不含有毒的甲醇,但含有刺激性气味的乙酸。
二保存条件:室温保存,至少一年有效。
注意事项:可以使用枪头盒或适当大小的培养皿作为染色和脱色的容器。
本染色液呈酸性,有轻微腐蚀性,使用时请作必要防护。
为了您的安全和健康,请穿实验服并戴一次性手套操作。
三使用说明:1. 常规染色脱色方法:a. 电泳结束后,取凝胶放入适量考马斯亮蓝染色液中,确保染色液可以充分覆盖凝胶。
b. 置于水平摇床或侧摆摇床上缓慢摇动,室温染色1小时或更长时间。
注:具体的染色时间取决于凝胶的厚度和染色时的温度。
凝胶较厚,温度较低,则染色时间宜适当延长。
凝胶较薄,温度较高,则染色时间可以适当缩短。
通常染色至凝胶的颜色和染色液的颜色非常接近,在染色液中几乎看不清凝胶时,可以认为已染色充分。
染色2-4个小时或更长时间不会对最终的染色效果产生负面影响。
c. 倒出染色液。
染色液可以回收重复使用至少2-3次。
d. 加入适量考马斯亮蓝染色脱色液,确保脱色液可以充分覆盖凝胶。
e. 置于水平摇床或侧摆摇床上缓慢摇动,室温脱色4-24小时。
期间更换脱色液2-4次,直至蓝色背景基本上全部被脱去,并且蛋白条带染色效果达到预期。
通常蛋白条带在脱色1-2小时后即可出现。
注:脱色期间可以在脱色液中加入一片吸水纸,可以使部分染料吸附在吸水纸上,加快脱色。
脱色时间过长也会导致蛋白条带的颜色变浅。

初二练习题制作希腊风味烤羊排配迷迭香英语作文

初二练习题制作希腊风味烤羊排配迷迭香英语作文Today, I would like to share with you a delightful recipe for Greekstyle roasted lamb chops with rosemary. This dish is not only flavorful but also relatively easy to prepare, making it a perfect choice for a special dinner or gathering.To begin, gather all the necessary ingredients: lamb chops, olive oil, lemon juice, garlic, rosemary, salt, and pepper. Make sure the lamb chops are at room temperature before you start cooking. Preheat your oven to 400°F (200°C) to ensure it's ready when you need it.Next, marinate the lamb chops. In a bowl, combine olive oil, lemon juice, minced garlic, chopped rosemary, salt, and pepper. Mix well to create a flavorful marinade. Coat the lamb chops with the marinade, making sure each piece is well covered. Let them marinate for at least 30 minutes to allow the flavors to penetrate the meat.Once the lamb chops have marinated, place them on a baking sheet lined with parchment paper. Make sure to space them out evenly to ensure they cook evenly. Roast the lamb chops in the preheated oven for about 2025 minutes, or until they reach your desired level of doneness. Remember to flip them halfway through the cooking process to ensure they cook evenly on both sides.While the lamb chops are roasting, you can prepare a simple side dish to complement the dish. A fresh Greek salad or roasted vegetables would be an excellent choice to serve alongside the lamb chops.Once the lamb chops are done, remove them from the oven andlet them rest for a few minutes before serving. This resting period allows the juices to redistribute, ensuring a tender and juicy final result.To serve, plate the lamb chops and garnish with a sprig of fresh rosemary for an added touch of elegance. You can also squeeze a little fresh lemon juice over the lamb chops to enhance the flavors.In conclusion, this Greekstyle roasted lamb chops with rosemary recipe is a fantastic way to incorporate Mediterranean flavors into your cooking. Whether you're hosting a dinner party or simply craving a delicious meal, this dish is sure to impress. Give it a try and enjoy the delightful combination of tenderlamb chops infused with the aromatic flavors of rosemary. Bonappétit!。
ColiComplete 产品说明书

Page 1 of 2 ColiComplete ®AOAC Official Method 992.30General DescriptionColiComplete ® contains 5-bromo-4-chloro-3-indolyl-ß-Dgalactopyranoside (X-Gal) and 4-methyl umbelliferyl-ß-D-glucuronide (MUG). Discs are added to LST inoculated with selected dilutions of samples. Samples are incubated at 35–37 °C and examined after 24 and 48 ±2 h for confirmed total coliforms and after 30 ±2 h for confirmed E. coli results. ß-Galactosidase, from coliforms present in samples, cleaves X-Gal into 5-bromo-4-chloro-indoxyl intermediate which undergoes oxidation to yield water-insoluble blue dimer, visually detectable on disc or in surrounding medium as confirmed positive result for total coliform activity. ß-Glucuronidase, from E. coli present in samples, cleaves MUG into glucuronide and methyl umbelliferone which fluoresces under long wave UV light (366 nm) as confirmed positive result for E. coli presence.NOTE : As E. coli O157:H7 does not produce ß-glucuronidase, ColiComplete ® is not suitable for the detection of E. coli O157:H7.A. Sample PreparationPrepare appropriate serial dilutions as indicated in FDA Bacteriological Analytical Manual (BAM), or AOAC Official Methods of Analysis according to sample type.B. InoculationInoculate LST tubes with appropriate sample dilution series selected to determine MPN levels or presence/absence of total coliforms and E. coli in sample. Aseptically add a single ColiComplete ® disc to each tube. Incubate at 35–37 °C.C. Reading ColiComplete ®a. For total coliforms — After at least 24 h incubation, examine each tube for visually detectable blue color on disc or in surrounding medium. Presence of blue color indicates confirmed positive result for total coliforms.NOTE: A wide range of blue color intensity may be expected, depending on sample composition and microflora. All blue reactions are positive regardless of intensity of color.Reincubate at 35–37 °C. After additional 24 ±2 h re-examine. Continued absence of blue indicates negative result; presence of blue indicates confirmed positive result for total coliforms. Read and record the MPN code or presence/absence of total coliforms in the sample.b. For E.coli — After 30 ±2 h from start of initial incubation, examine tubes under long-wave UV light (366 nm). Fluorescent tubes indicate confirmed positive result for E. coli. Read and record the MPN code or presence/absence of E. coli in the sample.D. CONTROLSPositive and negative controls should be used to facilitate interpretation of MUG fluorescent reaction. Use one known positive E. coli tube and two negative controls - one non -E. coli /coliform tube (e.g., Klebsiella spp.) and one uninoculated media tube.NOTE: Use borosilicate glass tubes, flint glass gives fluorescence that may be misinterpreted for a positive result.Lit.

考马斯亮蓝法测定(实验报告)

考马斯亮蓝法测定苹果组织微量可溶性蛋白含量吴凡郭梦雨摘要:本实验以苹果果肉为研究对象,采取考马斯亮蓝比色法测定蛋白质的吸光度值,通过对果实可溶性蛋白提取缓冲液、缓冲液浓度、pH值、外源添加物对果肉可溶性蛋白提取效率的影响的研究,优化苹果果实可溶性蛋白含量测定方法,以期优化果实可溶性蛋白测定条件,为客观反映果实可溶性蛋白水平提供一种可行的方法。
结果表明:外源添加PVP和EDTA以是苹果可溶性蛋白提取率的主要影响因素。
实验最终确定的提取条件为0.1mol/L pH9.0 Tris-HCl提取缓冲液(内含1mmol/L EDTA和1% PVP),此条件下苹果果实可溶性蛋白的有效测定含量为34.93%。
关键词:苹果、考马斯亮蓝法、Tris-HCl缓冲液、外援添加物1 实验部分1.1 实验原理果蔬可溶性蛋白质含量(soluble protein content)是一个重要的生理生化指标,也是果蔬品质和营养的重要评价指标之一。
许多可溶性蛋白是构成果蔬中酶的重要组成部分,参与果蔬多种生理生化代谢过程的调控,与果蔬的生长发育、成熟衰老,抗病性、抗逆性密切相关。
考马斯亮蓝G-250在酸性游离状态下呈棕红色,最大光吸收在465nm,当它与蛋白质结合后变为蓝色,最大光吸收在595nm。
在一定的蛋白质浓度范围内,蛋白质-染料复合物在波长为595nm处的光吸收与蛋白质含量成正比,通过测定595nm处光吸收的增加量可知与其结合蛋白质的量。
蛋白质与考马斯亮蓝G-250结合在2min左右的时间内达到平衡,完成反应十分迅速;其结合物在室温下1h 内保持稳定。
该法是1976年Bradford建立,试剂配制简单,操作简便快捷,反应非常灵敏,灵敏度高,可测定微克级蛋白质含量,测定蛋白质浓度范围为0~1 000μg/mL,最小可测2.5μg/mL蛋白质,是一种常用的微量蛋白质快速测定方法。
但该方法线性范围窄,需要选择适宜的提取缓冲液及缓冲液浓度、pH值和外源添加物等,以使测定方法有较高的灵敏度,测定值与真值相近。

考马斯亮蓝溶液配制方法

考马斯亮蓝溶液配制方法嘿,朋友们!今天咱就来讲讲考马斯亮蓝溶液的配制方法。
这可是个挺重要的事儿呢!先来说说需要准备的东西哈,那就是考马斯亮蓝粉末啦,还有乙醇、磷酸等一些试剂。
就好像做饭得有食材一样,这些就是我们配制溶液的“食材”哟!咱先拿个合适的容器,就像个小碗似的。
然后把适量的考马斯亮蓝粉末放进去,这粉末看着不起眼,可作用大着呢!接着呢,再慢慢地把乙醇倒进去。
哎呀,你可别一下子倒太多啦,得一点点来,就像给花浇水似的,轻轻柔柔的。
然后呢,就开始搅拌啦,要把它们搅拌均匀,让粉末完全溶解在乙醇里,这过程就像是给面团揉匀一样。
等搅拌得差不多了,再加入磷酸等其他试剂。
这一步可不能马虎,加多少得把握好,就跟做菜放盐一样,多了咸少了淡。
加完后继续搅拌搅拌,让它们充分融合在一起。
你说这考马斯亮蓝溶液就像是一个小团队,各种成分就是团队里的成员,只有大家齐心协力,才能发挥出最大的作用呀!在配制的过程中,可得仔细着点,别粗心大意的。
要是不小心弄错了什么,那可就前功尽弃啦!就像盖房子,一块砖没放好,可能整座房子都不结实呢。
等溶液配制好了,就可以拿去用啦。
可以用它来做各种实验,看看蛋白质的含量啥的。
这就像是给我们的科学研究打开了一扇门,让我们能看到更多的奥秘。
你想想,要是没有这正确配制的考马斯亮蓝溶液,那些实验该怎么做呀?那不就像战士上战场没带武器一样嘛!所以说,这配制方法可得好好掌握。
朋友们,都记住了吗?其实配制考马斯亮蓝溶液也不难,只要用心去做,肯定能成功的。
就像我们生活中的很多事情一样,只要肯下功夫,就没有做不到的。
加油吧,让我们一起在科学的海洋里畅游,用这神奇的考马斯亮蓝溶液去探索更多的未知!。

规格 1L 5L
储存 室温 室温
产品描述
实验室常使用考马斯亮蓝染色法对凝胶上分离的蛋白进行染色,它既克服了氨基黑染色灵敏度不高的限制,又比银染简 便易操作。目前广泛用的考马斯亮蓝有 G250 和 R250 两种。其中考马斯亮蓝 G250 由于与蛋白质的结合反应十分迅速,常 用于蛋白质含量的测定。考马斯亮蓝 R250 与蛋白质反应虽然比较缓慢,但是可以被洗脱下去,所以可以用来对电泳条带染 色。
1)剥下电泳完毕的SDS-PAGE,或native-PAGE胶,(约10×10cm,厚度小于1mm),放在比凝胶稍大的可微波炉加热的带 盖塑料盒中(注意:一定要有盖以防止水汽蒸发过度);
2) 加入50ml染色液,放入微波炉里先用高火(微波炉最大“火”)加热1分钟,取出染胶盒放在水平摇床上,中速震荡3-5min。 倒掉染色液。
高火加热 1min,低火加热 3-5min,可一定程度恢复干裂的 PAGE 胶,但染色效果有一定毁坏。
操作步骤
1. 染色工作液的配制
本品是以 125×浓缩液的形式提供的,每瓶 8ml。 使用前只需要取一瓶 8ml 的染色原液用去离子水或者蒸馏水稀释到 1L,混匀后即为染色工作液,室温保存即可。
2. 染色步骤
