True about immunoglobulins is:
|A||H chain is same for every class|
|B||There are only two types of light chains|
|C||Antigen combining site is carboxy terminus|
|D||Molecular weight of light chain is 50,000|
1. Class specific determinants are present on constant heavy chain region.
2. There are two light chains (kappa or lambda) and two heavy chains in an antibody molecule.
3. The antigen-binding (Paratope) site is present at the amino terminal end.
4. The molecular weight of light and heavy chain is 25000 and 50000 respectively.
