Abstract
A method for detecting prostate specific membrane antigen (PSMA) in serum by immunoassay including the steps of capturing PSMA from serum using a PSMA antibody and detecting the captured PSMA with an anti-&agr; -antichymotrypsin antibody. In a preferred embodiment, PSMA is captured using a PSMA antibody by diluting the PSMA antibody, coating a surface such as the surface of wells in a microtiter plate, with the resulting solution, blocking non-specific sites on the surface with albumin, diluting the serum with a blocking buffer and applying a diluted sample to the surface to capture PSMA. A preferred embodiment for detecting captured PSMA, includes the steps of removing non-captured material by washing the surface, applying anti-&agr; antichymotrypsin antibody diluted in a blocking solution such as albumin solution and detecting bound PSMA using peroxidase labeled anti-rabbit IgG and OPD substrate.
