title: Electrophoretic characterization of the hemoglobins in pocket gophers of the genus Thomomys.
abstract: 1. Hemoglobin phenotypes have been determined for closely related pocket gopher subspecies in the genus Thomomys from sea level and high altitude. 2. A single hemoglobin band was demonstrated for each gopher population with cellulose acetate membrane electrophoresis, with a mobility of 73% relative to human Hb-A. 3. Using polyacrylamide gel electrophoresis, a major Hb component (94% of the total Hb) showed a relative mobility of 68-69%; the minor Hb component showed a relative mobility of 74-75%. 4. The electrophoretic and physiological similarities of the gopher hemoglobins have persisted despite extreme differences in ambient PO2 in the habitats of each subspecies.
