Inhibition of anti-DNP antibody formation by high doses of DNP-polyacrylamide molecules; effects of hapten density and hapten valence.

High-dose inhibition of anti-DNP antibody formation by a series of DNP-polyacrylamide molecules of varying hapten density and hapten valence was measured. It was found that a molecule's inhibitory ability correlated directly with its hapten density, but not with its hapten valence nor with its own ability at optimal dose to stimulate an anti-DNP response.
