四聚物的结合是通过表面免疫球蛋白抗原受体，通过Fc受体结合抗体的很少量甚至没有。

Binding of the tetramers occurred by the surface immunoglobulin antigen receptor with little or no binding to antibody captured in the Fc receptor.

虽然有些儿童长大而不再对牛奶过敏，然而，他们一般有牛奶过敏免疫球蛋白e抗体针对抗原构象表位。

Children who have outgrown their milk allergies, however, usually have milk-specific IgE antibodies directed against conformational epitopes.

The IgM is really five IgG-type molecules that are linked together through disulfide bonds, such that their FC portions are all pointing in and their antibody binding portions are all pointing out.

gM是由五个IgG分子组成的,IgG分子之间通过二硫键连接,免疫球蛋白尾部的FC片段都指向内侧,而抗体的抗原结合位点都指向外侧
