Figure 6. Chromaffin cells expressing either sustained or inactivating BK currents are anoxia sensitive.

Figure 6

Aa and Ba, protocol used to identify AMC that expressed a sustained BK (A) or inactivating BK (B) current. Cells were initially held at −70 mV and briefly stepped to 0 mV for 50 ms (lower traces), before a final step to +80 mV for 500 ms. Both cells contained outward current that was reversibly suppressed by anoxia (a) as shown in Ab (for cell in Aa) and Bb (for cell in Ba). Traces shown for voltage step from −60 to +30 mV.
