An enzyme immunoassay for prostate-specific p30 antigen detection in the postcoital vaginal tract.

ABSTRACT

A sandwich enzyme immunoassay test utilising a mouse monoclonal antibody has been adapted for the sensitive detection of the p30 prostatic antigen in semen and in postcoital vaginal swabs. In liquid semen, p30 was still detectable at a 1/1,000,000 dilution, and it could still be detected on vaginal swabs 24 h postcoitus.
