gamma-Glutamyltransferase test as a new tool for identification of seminal stains.
A simple qualitative method for identification of seminal stains based on a high activity of gamma-glutamyltransferase (gamma-GTP) in human semen is described. It employs the release of alpha-naphthylamine from N-gamma-glutamyl-alpha-naphthylamide by the gamma-GTP action: alpha-naphthylamine couples with Fast Garnet GBC salt to produce a strong brownish-red color. The data on its simplicity, specificity, and stability show that the present method is suitable for medicolegal examination of seminal stains as a preliminary test.
