Rapid endocytosis was inhibited in cells dialyzed with GTP-γ-S. Capacitance recording of a control cell that underwent exocytosis during stimulation but that showed no rapid endocytosis afterward. GTP-γ-S (350 μm) was dialyzed into the cell via the patch pipette. In five of eight cells dialyzed with GTP-γ-S, there was little or no endocytosis present in the cells.
