title: Inhibitory effects of 4,4'-diisothiocyanostilbene-2,2'-disulfonate (DIDS) on the ADP-stimulated aggregation of gel-filtered bovine blood platelets.
abstract: The effect of DIDS, a specific inhibitor of anion transport in the erythrocyte membrane, on the ADP-stimulated aggregation of gel-filtered bovine blood platelets was examined. Marked inhibition of aggregation was observed at concentrations of more than 5 x 10(-5)M DIDS. On preincubation with platelets for 30 min, DIDS was more potent and significant inhibition was observed at concentrations of over 2 x 10(-7)M. Since ADP-stimulated aggregation of bovine gel-filtered platelets precedes the release reaction, these results suggest that an anion transport system in the plasma membrane is involved in platelet aggregation.
