P2X2/ P2X3 - Block by suramin on the Patchliner
Block of P2X2/3 receptors by suramin. Suramin at increasing concentrations (1 μM - 1 mM) was pre-incubated and then co-applied with 30 μM ATP. Full recovery from block was achieved upon washout (data not shown). Concentration response curve (right) for suramin block, IC50 = 28.0 ± 5.3 μM (n = 7).
