title: An interspecies approach to the investigation of the red cell membrane glucose transporter.
abstract: Glucose transport differs in red cells of various species. The following sequence of transport velocities was found: man greater than newborn pig greater than rat, dog greater than cattle greater than pig. No correlation was found between the amount of protein in band 3 and glucose transport activity. By contrast, a very clear peak in the band 4.5 region was found for newborn pigs, whereas adult pigs did not exhibit a corresponding peak in the electrophoresis. Thus further evidence is provided by our investigations in favour of band 4.5 region for glucose transport activity in red cells.
