Abstract
Sperm cells are stained according to processes that involve the combining of sperm cells with a fluorescent DNA selective dye at an elevated temperature in excess of about 40° C. The methods allow for a decreased staining time. The cells may thereafter be efficiently sorted according to common separation methods, including flow cytometry.
