Erythrocyte antigen, antibody and immunoimcompatibility of the erythrocyte blood group systems

ABSTRACT

The erythrocyte antigen, basically, is antigen of blood group systems and usually has 2 parts protein and lipid or glucid. The erythrocyte antigens usually exist along the life. However, they can be impaired when a person is aging or suffering a disease. The erythrocyte antibodies are immunoglobulines in the plasma. Most of them are IgM and IgG, little with IgA. Currently 23 erythrocyte group blood systems with 250 antigens have been found.
