ABSTRACT:
An immunoassay is disclosed where the label is an enzyme which converts a precursor into a cycling factor which in turn is interconverted in a cycling detection system. The detection system is amplified by the enzyme label constantly increasing the amount of cycling factors in the system. The system of NADP to NAD with NAD cycling to NADH and back is preferred.
