Abstract
Total arrest of cell membrane activity occurred after incubation of cultured fibroblasts for 2 h with the polycation DEAE-dextran. The immobilized cells resumed normal membrane undulations after exposure for 5 min to the polyanion dextran sulfate. The influence of DEAE-dextran on electrophoretic mobility was seen after 10 min of incubation and was eliminated by subsequent incubation with dextran of sulfate. Growth of the culture was not affected.
