Features identification of isoantigens in tissues at different seasons

N the study, it was studied that in the lymph nodes and muscles in the cold season, group-specific isoantigens are clearly detected within 3 months of their decay. When decaying a corpse in the warm season, group-specific antigens in organs are determined within 2 weeks from the moment of death of a person, then decay led to a decrease in the absorption capacity of antigens contained in them.
