Question

The Fc (Fragment crystallization) region of antibody is made up of
(A) Constant region of light chains
(B) Constant region of heavy chains
(C) Variable region of light chains
(D) Variable region of heavy chains​

Answer 1

Answer:

The amino-terminal variable or V domains of the heavy and light chains (VH and VL, respectively) together make up the V region of the ...

Answer 2

Answer:

In IgG, IgA and IgD antibody isotypes, the Fc region is composed of two identical protein fragments, derived from the second and third constant domains of the antibody's two heavy chains; IgM and IgE Fc regions contain three heavy chain constant domains (CH domains 2–4) in each polypeptide chain.
