Cytochemical detection of ABH antigens in human body fluids.
The use of the peroxidase-anti-peroxidase (PAP) technique has been described previously for the detection of cellular antigens and in particular ABO antigens from tissue samples (Pedal and Hülle 1984; Pedal and Baedeker 1985; Pedal et al. 1985). In this survey, the PAP method has been employed to study the detection of ABO antigens in cells from body fluids of particular interest to forensic science, namely buccal cells and vaginal cells. Also tested, but in a limited number, were mixtures of body fluids and semen samples. No false reactions were obtained from buccal cells, all samples corresponding to the ABO blood type of the donor. Preliminary results from vaginal cells, vaginal/buccal cell mixtures, and semen were encouraging but must be treated with caution due to the limited number tested. Vaginal smears contaminated with semen showed varying degrees of nonspecificity.
