Interactions Between Black Lipid Membranes and the Loosely Bound Proteins from Erythrocyte Membranes

Abstract

Abstract The loosely bound proteins from hum an erythrocyte membranes induce an up to more than 103-fold increase in the electrical conductivity of black lipid membranes made from oxidized cholesterol. The conductivity increase continues until the membrane breaks. Its magnitude insreases with in­ creasing protein concentration and salt concentration. The results are compared with earlier results obtained with the strongly bound proteins from erythrocyte membranes.
