The murine H-2.7 specificity is an antigenic determinant of C4d, a fragment of the fourth component of the complement system

Abstract

The S region of H-2 controls a polymorphism of the gamma-chain of C4 (gamma 1, gamma 2, and gamma 3) as shown by differences in their isoelectric points. The G region of H-2 was defined by the presence of an alloantigen (H-2.7) on erythrocytes and serum. We found that antisera to H-2.7 immunoprecipitated C4 and no other protein from mouse EDTA-plasma… (More)
