Abstract
A specific binding assay method employing, as a labeling substance, a reversible trypsin inhibitor for the detection of a hapten. Competition between the hapten to be determined and hapten trysin inhibitor conjugate for antibody to the hapten, in the presence of enzyme, followed by addition of enzyme substrate provides an effective method for hapten analysis. The preferred trypsin inhibitor is a protein having a molecular weight range of 2,000-75,000. The preferred ratio of the hapten to the inhibitor in the conjugate is between 1:1 and 3:1.
