Outlined in the paper are outlooks for determining a group affiliation of sperm in traces, left in material evidence, within forensic biological expertise. A technique is suggested to separate the spermatozoids from the vaginal epithelium cells--it has been used up to now in genetics alone. The method involves the available reagents and does not need any(More)
A comprehensive series of experiments was undertaken to find the reasons why the cigar-butt stuff, removed from accident places for investigation at forensic-biological laboratories, affects different sera. A number of such reasons were established. Methods are suggested to eliminate the cigar-butt impact with the aim of ensuring the most accurate results(More)
A method for simultaneous detection and identification of the blood in stains on material evidence has been tried. Previously these two procedures were carried out in succession and took 2 days, while the new method takes 2-10 min. The method is highly sensitive and specific. Positive results were obtained only with human blood. The method is recommended(More)
A series of experiments using agglutination inhibition reaction and material extraction in PBS with pH 7.2 (phosphate-buffer-sedin) has been made to detect antigens of the GM system in the teeth. Parameters of the test material/serum ratio are proposed. In parallel, control specimens of blood were examined. The results of the experiments suggest that(More)
Difficulties appearing in determining hair group were the reason for conducting this research for the purpose of finding additional possibilities to solve the mentioned problem. It was established that the preliminary cell coloring, related with determination of hair sex, does not influence a consequent detection of antigens. Methods or the fixation of(More)
