    Abstract

    Although elevated acid phosphatase (AP) activity in vaginal fluid is a consistent indicator for semen, differentiation between vaginal AP and seminal AP provides a more meaningful result. Detection of seminal AP in mixtures of vaginal AP, feces, and blood is accomplished by starch gel electrophoresis, employing the substrate thymolphthalein monophosphate as a selective visualization agent. Genetic phosphoglucomutase isoenzymes are simultaneously separated by this method and allow differentiation in some semen/vaginal fluid mixtures.
