This allows a b cell to bind to a specific antigen the main functions of b cells are. The above briefly described the five biological functions of antibodies, which are a specific function with the antigen, activation of complement, binding of fc. Antibodies play an important role in the immune system. For example, antiprotein antibodies tend to have flat antigenbinding sites while those of antipeptide antibodies have a groovelike shape, in which peptides are buried.
