In Vitro Use Guide
To measure BK activation whole-cell patch clamp on HEK293, expressing BKalpha, was used. The Ca2 concentration in the pipette solution was fixed at pCa 6.5 using a Ca2-EGTA buffer. Depolarization from -60 to -30 mV induced outward currents in both native HEK and HEKBK1. Application of PiMA in a concentration range of 1 to 10 uM increased outward currents in a dose-dependent fashion in HEKBK1 but did not change in native HEK.
