SR 33805 oxalate blocks L-type Ca2+ currents in Xenopus oocytes. A. Time course of L-type channel (CaV1.2+a2d1+ß1a) activity before and during applications of 1 µM SR 33805 oxalate (ab141868) as indicated, and upon wash. Holding potential was -80 mV and currents were elicited every 10 seconds by 100 ms ramp to +60 mV. B. Superimposed current traces of L-type currents before and during applications of 1 µM SR 33805 oxalate, taken from the experiment in A.
