Dynamics of Inhibition of Immunoprecipitin by Hapten (Drug)
In the drug assays, the conjugate is prepared by linking several hapten (drug) residues
to a high molecular weight carrier. The conjugate competes with the free drug
(hapten) in the sample for available binding sites on the antibody. Increased drug in
the sample results in a decrease in the formation of insoluble complexes. Figure 3.5
illustrates the conjugate antibody reaction in the presence of hapten (drug).
