Chimpanzee Blood Groups: Demonstrated with Isoimmune and Cross Immune Sera

Abstract
Two simian-type erythrocyte blood factors of chimpanzees, Gc and H0, are described. The serological charac- teristics and the population analysis of these and of the other 6 recently described blood group specificities are presented, which determine the existence in chimpanzees of the simian-type blood group systems, V-A-B, OE-F-H, and a system for the factor Gc. The establishment of the "Holloman Panel" for standardization of simian erythrocyte, leukocyte and immunoglobulin reagents is an-nounced.
