Effect of NEM on prepulse facilitation of Cav2.2a and
Cav2.2b channels. (A) Prepulse facilitation
of Cav2.2b channels, recorded as in Fig.
2A in the presence and absence of 50 μM NEM.
(B) Prepulse facilitation of Cav2.2b
channels, measured as in Fig. 2A in the presence
and absence of 50 μM NEM. (Scale bars: A, 1.5 nA, 4
ms; B, 0.2 nA, 4 ms.)
