[Detection of ABO and GM system antigens in the teeth]

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 detection of Gm antigens in the teeth is feasible. In some cases this may raise an identification level of the expert conclusions. The above technique can be used for investigation of the bones.
