[The detection of ABO system antigens in bone, nail and tooth fragments]

Fragments of the bones, nails, and teeth were examined in 12 forensic biological departments of bureaus for forensic medical expert evaluation of the Russian Federation. A total of 790 experiments were carried out with 145 bones, 5 teeth, and nails from 12 cadavers. In the overwhelming majority of cases the experiments were carried out with control investigations of blood, hair, salivary, and sweat samples. Modifications of the absorption-elution method were used to detect the AB0 antigens, these modifications involving all stages of the test (fixation, fat extraction, medium for elution, reagents, time factors in absorption and elution, etc.). Analysis of the data permitted the authors to make some conclusions and offer recommendations for practical biological experts.
