[The comparative characteristics of the physicochemical and structural-functional properties of hemoglobin in a number of vertebrates]. / Sravnitel'naia kharakteristika nekotorykh fiziko-khimicheskikh i strukturno-funktsional'nykh svoistv gemoglobina v riadu pozvonochnykh.

Using isoelectrofocusing within pH gradient 6-8, studies have been made on microheterogeneity of haemoglobins from various vertebrates. Phylogenetic evaluation of oxygen affinity of the main and minor electrophoretically pure haemoglobin fractions is given. It was shown that oxygen affinity of the haemoglobins is related to the ratio between dicarboxylic and basic amino acids.
