Interactions between black lipid membranes and the loosely bound proteins from erythrocyte membranes

The loosely bound proteins from human 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 increasing protein concentration and salt concentration. The results are compared with earlier results obtained with the strongly bound proteins from erythrocyte membranes.
