The TAA recovery kinetics in the continuous presence of ASP. A, The experimental protocol. TPentA (2 mm) was applied for 2 sec in the continuous presence of ASP (100 μm) when the inward current gained its stationary level, ICS. The solution exchange at the termination of TPentA application was fast. B, Representative examples of the current recovery after termination of TEA (5 mm), TPA (2 mm), TBA (2 mm), and TPentA (2 mm) application in the continuous presence of ASP. The solid lines are double-exponential fittings of the recovery kinetics in the cases of TEA and TPentA (τfast = 40 msec,τslow = 440 msec, andAfast = 0.68 for TEA;τfast = 74 msec,τslow = 987 msec, andAfast = 0.68 for TPentA) and a single-exponential fitting in the case of TBA (τ = 368 msec).
