ABO Blood Group Antigen on the Human Liver Ribosome

Effect of Blood Group Substances Decomposing Enzyme and Ribonuclease on the Human Liver Ribosome

Abstract

Human liver ribosomes were separated by Takanami's method, and the blood types were evaluated through the hemagglutination inhibition test applied to the ribosomes. Ribosomes obtained from individual of type B absorbed anti-B serum specifically. These blood group antigens were not influenced by treatment with RNase but released through the action of blood group substances decomposing enzyme.
