Fig. 2.
pH activation and amantadine sensitivity of A/M2, BM2, truncated A/M2, and chimeric BM2 ion channels. Representative recordings of these ion channels are shown. Amantadine sensitivity was evaluated by bathing oocytes in pH 5.5 bathing solution containing 100 μM amantadine, starting when the oocytes displayed maximum inward current (red).
