BLOOD GROUP ANTIGENS

blood group antigens: translation

The set of cell surface antigens found chiefly, but not solely, on blood cells. More than fifteen different blood group systems are recognized in humans. There may be naturally occurring antibodies without immunization, especially in the case of the ABO system, and matching blood groups is important for safe transfusion. In most cases the antigenic determinant resides in the carbohydrate chains of membrane glycoproteins or glycolipids. See also Rhesus, Duffy, Kell, Lewis and MN blood groups.
