[Studies on the Concanavalin A-receptors of rabbit erythrocytes and of erythyrocyte shadows using immunoelectron microscopy].
The authors report on the immuno electron microscopic demonstration of Concanavalin A-receptors on the erythrocyte membrane. Immuno freeze-etching studies evidenced a focal arrangement of Concanavalin A-receptors on intact erythrocytes as well as on erythrocyte ghosts. Obviously hemolysis by distilled water does not produce changes in the pattern of distribution of Concanavalin A-receptors whereas slight aggregation of plasma membrane intramembraneous particles occured. No unambigous spatial relationship between Concanavalin A-receptors and the plasma membrane intramembraneous particles (intrinsic proteins) of erythrocytes could be observed.
