Figure 2. Specificity of the effects of AP and trypsin on whole-cell currents of single M-1 cells.

The experimental protocol was similar to that described in the legend to Fig. 1 and drugs were applied as indicated. A, sequential application of reverse peptide (RP) and AP (20 μM). B, effect of trypsin (20 μg ml⁻¹) in the presence and absence of trypsin inhibitor (40 μg ml⁻¹). C, application of AP in the presence of trypsin inhibitor.
