Protein patterns of red cell membranes from different mammalian species

Abstract

1. 1. Erythrocyte membrane proteins of human, rat, rabbit, pig, ox and sheep have been solubilized by n-butanol fractionation of aqueous ghost suspensions.

2. 2. The solubility of the different protein solutions and their lipid composition has been studied.

3. 3. Sedimentation in an analytical ultracentrifuge and disc electrophoresis in polyacrylamide demonstrated that the protein composition of the erythrocyte membranes from the mammalian species is markedly different.
