Abstract
A quick and simple immunoassay technique applicable to the determination of large molecules like proteins, polynucleotides and others involves labelling competitive immunospecies with an enzyme as signal generator. This enzyme can be converted to the corresponding apo-enzyme form and its regeneration, upon addition of a suitable co-factor, is inhibited by complexation when the labelled specie is reacted with its immunopartner. The degree of complexation is therefore ascertained by measuring the extent of regenerated activity.
