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.
