[The detection of the cholesterol of the erythrocyte plasmalemma by using a latex marker].

Using a new specific cholesterol marker (SCM) and scanning electron microscopy, the distribution of cholesterol in the plasmalemma of rabbit and human erythrocytes was studied. Investigation of SCM linking with the erythrocyte membranes with different cholesterol/phospholipid indices shows that the increase of cholesterol/phospholipid index of the erythrocyte membrane correlates with the increase in the number of SCM particles on the erythrocyte surface.
