Estimation of cell depolarization produced by hypoxia. (A) Single channel amplitude levels of the high conductance (TASK-1/3-like) channel were determined at each O2 level in the 0-1 day and 16-18 day groups. Each point is the mean±SE of 4-5 determinations. (*) = significant difference (p<0.05). (B) To correlate change in single channel amplitude with change in membrane potential, amplitude levels of the high conductance channel (TASK-1/3) was determined at various pipette potential and plotted. (C) From this linear relationship in (B), the mean zero-current potential (Em) was calculated and plotted.
