Allelic variants of antibodies are known as:

Ileum

Which of the HV domains is the most variable?

IgM is found at high concentrations in the serum, and is found as a very high molecular weight complex. This high molecular weight complex is composed of:

When a B cell differentiates into a plasma cell, it goes from expressing membrane-bound IgM to making mostly the secreted form of IgM. A deletion of the first polyadenylation (Secretory coding) site in the μ heavy chain gene would prevent activated B cells from making the secreted form of IgM.

B cells bind to carbohydrates and proteins
