Abstract

A nonprecipitable antibody to a haptenic group has been purified from equine serum. It is a 7S β2δ immunoglobulin with high affinity for the specific hapten and two binding sites per antibody molecule. These results rule out univalence and low affinity as explanations of the nonprecipitability of this antibody.
