Globin prepared from hemoglobin of adult tupai (Tupaia glis) was separated into alpha and beta polypeptide chains by CM-cellulose column chromatography. The S-aminoethylated alpha polypeptide chain and S-carboxymethylated beta polypeptide chain were each digested with trypsin, and the sequences of all the peptides thus obtained were established. The ordering of these tryptic peptides in the alpha and beta polypeptide chains was deduced from the homology of their primary structures with that of human adult hemoglobin. In this way the primary structures of the alpha and beta polypeptide chains of tupai hemoglobin were established; 27 amino acids in the alpha polypeptide chain and 26 in the beta chain differ from those in human adult hemoglobin.
