实验概要This method involves coupling an IgG anti-IgM antibody to protein A or G beads (see method below). These beads can then be used in the normal immunopreciptiation procedure using the IgM antibody. The IgM will bind to the beads by binding to the anti-IgM antibody.The procedure below describes how to couple the anti-IgM antibody to the protein A or G coated beads using dimethylpimelimidate (DMP).主要试剂1.&nb......阅读全文

igg和igm区别
igm为免疫球蛋白m，是人体中抗原刺激后出现最早的抗体，是分子量最大的抗体，不能通过胎盘输送给胎儿。一旦感染，快速产生，igm阳性说明感染处于急性期，出现的早，消失的也早。igg为免疫球蛋白g，抗体的分子量小，抗体产生的比较晚，可以通过胎盘输送给胎儿，对胎儿起保护性作用。如果监测到igg，说明感染已
IgG有什么作用
具有抗体活性的动物蛋白。主要存在于血浆中，也见于其他体液、组织和一些分泌液中。人血浆内的免疫球蛋白大多数存在于丙种球蛋白（γ-球蛋白）中。可分为五类，即免疫球蛋白G（IgG）、免疫球蛋白A（IgA）、免疫球蛋白M（IgM）、免疫球蛋白D（IgD）和免疫球蛋白E（IgE）。其中IgG是最主要的免疫球蛋
