功能
The basic structure of IgG molecule is composed of four polypeptide chains, that is, from the same two small molecular weight peptides (referred to as light chain,Light chain, L chain, the relative molecular mass of about 25,000) and two identical large molecular weight peptides (called heavy chain, heavy chain, H Chain, relative molecular mass of about 55,000) composed. A natural two heavy chains of IgG molecules are always the same. The goat IgG antibodies can specifically recognize the heavy Chain.风险提示:丁香通仅作为第三方平台,为商家信息发布提供平台空间。用户咨询产品时请注意保护个人信息及财产安全,合理判断,谨慎选购商品,商家和用户对交易行为负责。对于医疗器械类产品,请先查证核实企业经营资质和医疗器械产品注册证情况。
文献和实验当FITC在碱性溶液中与抗体蛋白反应时,主要是蛋白质上赖氨酸的r氨基与荧光素的硫碳胺键(thiocarbmide)结合,形成FITC-蛋白质结合物,即荧光抗体或荧光结合物。一个IgG分子中有86个赖氨酸残基,一般最多能结合15~20个,一个IgG分子可结合2~8个分子的FITC,其反应式如下FITC-N=C=S + N-H2-蛋白质 → FITC-NS-C-N-H2-蛋白质常用Marsshall(1958)法标记荧光抗体,也可以根据条件采用Chadwick等标记法或Clark
