Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective.
Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O and centrifuge if not clear. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid.
Extended Storage after Rehydration: Aliquot and freeze at -70°C or below. Avoid repeated freezing and thawing. Alternatively, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid.
Expiration date: one year from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.
Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6
Stabilizer: 15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free)
Preservative: None (Warning: Use of sodium azide as a preservative will substantially inhibit the enzyme activity of horseradish peroxidase.)
Suggested Working Concentration or Dilution Range:
1:500 - 1:5,000 for immunohisto/cytochemistry
1:5,000 - 1:100,000 for ELISA and Western blotting with chromogenic substrates
1:10,000 - 1:200,000 for Western blotting with ECL substrates
Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.

文献和实验位。 IF(免疫荧光检测)是采用荧光素标记物作为探针,形成的抗原抗体复合物上带有荧光素,在荧光显微镜下,受激发光的照射后发出一定波长的荧光,从而对细胞、组织中的抗原进行定位或定量。 表 1 IHC/ICC与IF特点对比 IHC/ICC 与 IF 染色中使用的抗体主要为一抗与二抗,根据是否选用二抗以及二抗标记物类型可形成多种不同的检测系统。信号放大是免疫组化实验中的重要步骤,信号放大可以使目标蛋白质的信号从微弱到明显,从而更容易被观察和定量。现有的信号放大技术多为链霉亲和素-生物素法,该方法基于链酶亲和
FITC标记的B抗体染色,根据两种抗体的动物种属不同,可用直接法也可用间接法,结果A抗原呈现橘红色荧光,而B抗原呈现黄绿色荧光。在应用中,常用的方法是免疫荧光组织化学中间接法和SABC-Cy3法相结合。例如,在实验设计时,选择小鼠抗大鼠A和兔抗大鼠B作为两种不同的特异性一抗,相匹配的二抗分别为FITC-抗小鼠IgG和生物素化―抗兔IgG。进行双重染色时,由于两种一抗种属来源不同,可把一抗混合使用。孵育结束后洗涤未结合的一抗,滴加二抗时,先加人生物素化―抗兔IgG(二抗)孵育,洗涤后,滴加SABC-Cy
实验流程:多靶点免疫荧光染色的实验操作与普通单标记免疫组化流程相似。试剂盒中的荧光染料可以在HRP酶的作用下将信号共价结合到抗原上,随后即可衔接下一轮单标染色,直至全部标记完成,即可复染DAPI后封片观察。1.脱蜡水合:1)新鲜二甲苯浸片10min,重复3次。2)梯度乙醇浸片,100% 5min;95% 5min;70% 2min。3)灭菌水洗片1min,重复3次。4)10%中性福尔马林浸片10min,灭菌水洗片1min,重复3次。2.微波修复:1)将脱蜡水合后的玻片置于修复杯中,用抗原
