Rhesus lymphocyte alloantigens. III. Identification of new antigens.

Rhesus monkey lymphocytotoxic alloantisera were tested in 437 random unrelated monkeys and in members of 19 pedigreed families. Groups of sera or individual sera identified 11 specificities. Genetic analysis of the associations of these antigens revealed behavior consistent with the current concept of the major histocompatibility complex of several mammalian species including man in that the antigens could be grouped into two series of closely linked co-dominantly expressed alleles.
