Forensic DNA: Sperm Detection and Separation
The detection of sperm and separation of sperm cells from the victim's DNA is crucial to identifying and characterizing the perpetrator's DNA profile. Improved automation of sperm detection and separation will enable more rape kits to be processed in a timely manner to help solve sexual assault crimes more effectively. Traditionally sperm cells are identified visually in evidentiary samples through light microscopy. New techniques are under development to aid improved visualization of sperm heads and tails with fluorescent staining as well as sperm cell isolation through laser capture microdissection.
