Bioluminescence Enhanced Enzyme Immunoassay. New Ultrasensitive Detection Systems for Enzyme Immunoassays, II.

Abstract

Ultrasensitive bioluminescence immunoassays for the determination of peptides and proteins (illustrated with human urinary kallikrein, bradykinin and the determination of human urinary kallikrein antibody titers) have been developed. The usable ranges of the standard curves are from 5 pg to 5000 pg per liter. The relative intra-assay coefficients of variation of the tests were between 2 and 6%, and the interassay coefficients of variation between 4 and 12%.
