Indefinite storage of dried Gm and Km (Inv) antigens: (examination of bloodstains 33 years old).
We confirm the great stability of the A and B antigens in dried blood, and the markedly lesser stability of antigen H. We demonstrate that it is possible to determine the immunoglobulin groups Gm(1), Gm(10) and Km(1)--formerly Inv(1)--in bloodstains 29 to 33 years old.
