ABSTRACT:
Reagents for use in binding assays, particularly immunoassays, to determine diphenylhydantoin and for preparing reagents employed in such assays, including .beta.-galactosyl-umbelliferone-diphenylhydantoin conjugates, diphenylhydantoin immunogens, and N.sup.1, N.sup.3 and o-phenyl derivatives of diphenylhydantoin for preparing same. N.sup.1 and N.sup.3 -.omega.-aminoalkyl and o-(.omega.-aminoalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to a .beta.-galactosyl-umbelliferone derivative to form labeled conjugates useful in homogeneous or heterogeneous binding assays. N.sup.1 and N.sup.3 -.omega.-carboxyalkyl and o-(.omega.-carboxyalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to an immunogenic polyamino acid to form immunogen conjugates against which diphenylhydantoin-specific antibodies can be raised.
