Electrophoresis of concanavalin A receptors along embryonic muscle cell membrane

Abstract
Fluorescent concanavalin A (con A)-labeling [of Xenopus laevis] showed that an electric field of 4 V/cm grossly redistributed con A receptors along the plasma membranes of living muscle cells within 4 h. This field produced a voltage drop of 12 mV across these 30 .mu.m-wide cells. The movement of receptors was independent of cell metabolism and seemed to be electrophoretic in nature.
