Progress in rhesus histocompatibility typing resulting from the Second International Nonhuman Primate Histocompatibility Workshop (1973).

The Second International Nonhuman Primate Histocompatibility Workshop permitted comparison of rhesus monkey alloantisera developed in various laboratories on a single common panel of related and unrelated monkeys. Analysis of the data permits the conclusion that at least nine specificities are recognized by more than one laboratory, including six at the first locus and three at the second locus.
