A comparison of the electrophoretic haemoglobin patterns of the vertebrates.

A comparative study of the haemoglobins of 648 animals distributed over 300 species of vertebrates and belonging to different classes has been made by horizontal starch gel electrophoresis is tris EDTA-borate pH 8.6. Multiple haemoglobins were found within the different classes. The percentage of multiple haemoglobins varies from class to class. The frequency-distribution of the mobility values of haemoglobins is rather specific for the different classes and in certain instances for the different orders.
