Question

Which of the following antibody is pentamer? (A) IgA (B) IgD (C) IgE (D) IgM

Tardigrade Admin · Accepted Answer

IgM is the largest antibody in human circulatory system. It is pentameric in nature, i.e. 5 Ig molecules covalently link together via disulphide bonds. As each monomer has 2 binding sites, so IgM has a total of 10 binding sites.
