Figure 3. Weak effects of membrane stretch on LKbg channels under the direct inhibition by PIP2.
A–C, representative traces of i-o recording obtained at different PIP2 concentrations (1, 2 and 5 μm). D, summary of normalized open probabilities (Po) measured under the constant negative pressure (−27 mmHg) at different PIP2 concentrations (n = 3–5).
