G01N 33543 G01N 33573 G01N 33574 G01N 33577
US Classification:
435 74
Abstract:
The present invention relates to the field of cancer immunoassay. Specifically, a new immunoassay method for prostate specific antigen (PSA) is presented. Also presented is a complex which resembles a complex of PSA and. alpha. -antichymotrypsin (ACT) that can be used as a calibrator or control in an immunoassay for PSA. Further presented is a method for fractionating polyclonal antibodies, to PSA, into those which bind epitopes that are masked by the binding of PSA to ACT and those which do not bind such epitopes.
