Abstract
Summary
The 2 hemoglobins of the turtle, Pseudemys scripta elegans, were prepared by means of a continuous flow electrophoresis. Both hemoglobins bound oxygen in a molar ratio of 1:1 with respect to iron. They have identical absorption spectra in the visible region but differ in isoelectric point, resistance to alkali, and in sedimentation constant. Physiochemical evidence is presented which indicates that these hemoglobins interact in mixtures.
