A cell adhesion-inhibiting activity was released by sonication of purified plasma membranes from Polysphondylium pallidum aggregation-competent cells. The activity was found to be periodate-sensitive but insensitive to trypsin treatment and relatively heat-stable. Adhesion of Dictyostelium discoideum cells was not affected by the released factor suggesting its species specificity. © 1983.
