Changes in plasma complement C4 and factor B allotypes after liver transplantation.
Plasma complement allotypes for C4 and factor B were determined in 21 patients before and after liver transplantation together with donor typing. In 17 transplantations allelic differences between the patient and the donor could be shown. In all cases the patient's C4 and factor-B types converted to that of the donor, showing that the liver is the major source of plasma complement C4 and factor B.
