B cells of the immune system become plasma cells when activated by the binding of a specific antigen on its antibody surfaces.
Where are AB and Rh antigens located?
Red blood cells (erythrocytes) have certain proteins on their surface, called antigens. Also, your plasma contains antibodies which will attack certain antigens if they are present. ABO and rhesus are both types of antigens found on the surface of red blood cells.
