title: Comparison of p30 and acid phosphatase levels in post-coital vaginal swabs from donor and casework studies.
abstract: The application of p30 detection to casework analysis of seminal traces on vaginal swabs is reported and compared with the levels of acid phosphatase determined. A simple crossed-over immunoelectrophoresis system was used for batch identification of swab extracts using a commercially obtained anti-p30 serum. Positive p30 results were obtained in less than 20% of the casework swab extracts, but they provide conclusive proof of the presence of semen which is a substantial advantage over the quantitative determination of acid phosphatase.
