Apamin Does Not Inhibit Human Cardiac Na+ Current, L-type Ca2+ Current or Other Major K+ Currents
Figure 1
The endogenous K+ currents of HEK 293 cells.
(A) The representative tracing obtained with ramp protocol shown in the inset at time point indicated by arrow a in (B). The pipette and bath solutions are the same as the ones used in measuring ISK2. (B) The time course of ISK2 measured at 0 mV. (C) The representative tracings obtained with the pulse protocol shown in the inset with the pipette and bath solution used in measuring IKs. (D) The representative tracings obtained with the pulse protocol shown in the inset with the pipette and bath solutions used in measuring IKr, IK1 and Ito.
