TABLE 2.

Midpoint of activation (V_1/2) and steepness degree (V_S) of conductance-voltage relationship of K_vAP in function of time, temperature, and state (mV)

V_1/2 (top, normal) and V_S (bottom, italic) are presented for different conditions of time, temperature, or holding potential for the lipid conditions indicated. Unless specified, the voltage was held at −100 mV during the experiments. The number of experiments ranged from n = 2 to 5, errors are S.D.
