Abstract
The present invention relates to dual analyte enzyme immunoassays for assaying two antigens in a single liquid sample wherein the two immunoreactions are carried out simultaneously and wherein subsequently the two enzyme reactions occur simultaneously. Suitable enzyme/substrate pairs are beta-galactosidase/nitrophenyl-beta-D-galactoside (p- an/or o-) and alkaline phosphatase/phenolphthalein monophosphate.
