Detection of p30 antigen in sexual assault case material.

A sandwich enzyme immunoassay for the detection of p30 prostate specific antigen was applied in 52 forensic cases. In each case, immunoassay results were compared with those of the search for spermatozoa and prostatic acid phosphatase analysis. The results indicate that the p30 assay gave no false positive and fewer false negative reactions than the acid phosphatase test.

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

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.
