    Abstract

    Contamination of semen by saliva can result in the alteration of seminal phosphoglucomutase (PGM1) isozyme patterns. The alteration is characterized by the gradual loss of the a and b isozyme bands with the concomitant generation of anodal bands; eventually, all PGM activity is lost. The conversion of PGM isozyme patterns has been shown to be due to a dialyzable heat-labile factor in saliva and a nondialyzable heat-labile factor in semen. The implications of this conversion for PGM typing in sexual assault evidence are discussed.
