| 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. |
