The effects of P2 receptor antagonists on oscillating currents. The P2 receptor antagonists suramin and PPADS (10-4 M) were applied either 2 min after oscillations were induced by continuous application of 10-4 M (a, b) ATP or (c) UDP or (d) 5 min before application of 10-4 M UTP to SPA (a, b) or LPA (c, d) dissociated smooth muscle cells voltage-clamped at -50 mV. The horizontal bars indicate agonist and antagonist applications. The arrow on the left-hand side of each trace indicates zero holding current.
