Antibody Structure Problem Set

Problem 4. Antigen epitopes

The epitope is defined as the part of the antigen that is recognized by antibody. The structural studies using hen egg white lysozyme as an antigen show that the epitope is:

A.	a single amino acid
B.	continuous, or limited to a single stretch of amino acids
C.	discontinuous, or can include amino acids from non-adjacent stretches of antigen amino acids
D.	the entire antigen
