beta-Globulin variants in two species of monkeys

VARIOUS β-globulin types have been demonstrated, using starch-gel electrophoresis, in several species of mammals, namely, man1, cattle2, sheep3, goat4 and horse5. The present communication reports the discovery of similar variations in two species of monkey, Macaca mulatta and M. irus. Variations in the monkey β-globulins were initially detected by paper electrophoresis using barbital buffer at pH 8.6. However, the β-globulins were much better resolved when starch-gel was used instead of paper.
