Genetic Markers in Human Semen. II: Quantitation of Polymorphic Proteins

Semen evidence is almost always present in cases involving sexual assault. The typing of genetic markers in this evidence material can be very valuable in the investigation and prosecution of these crimes. In many cases the victim of the assault cannot identify the assailant and in these cases genetic information gained from the semen can be used to include or exclude potential suspects. Even when the victim can identify the assailant, genetic typing information can provide important independent corroborating evidence. It is therefore clear that more extensive genetic characterization of semen evidence would be beneficial.
