Question

Quizplus · Accepted Answer

A conformational epitope is when the determinant site that stimulates antibody formation is created through the folding of the primary chain into a specific three-dimensional shape. This is different from a linear epitope which is a continuous sequence of amino acids in the primary chain. A hapten is a small molecule that can also stimulate antibody formation but must be attached to a larger carrier molecule because it is too small to be recognized on its own. Valence refers to the number of binding sites on an antigen that can interact with antibodies.
