Structure of antibodies is composed of -
Antibody or immunoglobulin are glycoproteins molecules consisting of four polypeptide chains. - two identical heavy chains ( H) , molecular weight > 50 kDa. - two identical light chains (L), molecular weight > 25kDa. - the heavy chains are of five types called alpha, gamma, delta , epsilon and mu. - light chains are similar in all class of immunoglobulins.
