Study Notes
Antigens on RBCs and ABO Blood Groups
- Antigens on the surface of RBCs (Red Blood Cells) are named A and B.
- The ABO blood groups were discovered by Karl Landsteiner.
- Karl Landsteiner described the ABO blood group system based on the agglutination reaction.
- Karl Landsteiner classified the blood groups into A, B, AB, and O based on the presence of specific agglutinogens (A and B antigens) and agglutinins (anti-A and anti-B antibodies).
- The corresponding antibodies in the plasma are anti-A and anti-B.
