Erythrocyte antigen-antibody and immunoincompatibility of 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 from a disease. The erythrocyte antibodies are immunoglobulines in the plasma. Most of them are IgM, IgG and little with IgA. Currently, 23 erythrocyte blood group systems with more than 250 antigens have been found.
