Figure 8

Cation-anion selectivity of L-ArgR channels. The figure shows current elicited by voltage ramps across a lipid bilayer (DOPS:DOPE, 1:1) containing several channels from the Sephacryl S-300 step, in the presence of a 4-fold gradient of NaCl across the membrane (cis and trans chambers contained 100 and 25 mM NaCl respectively). The reversal potential is -14 mV, corresponding to weak cation selectivity (PNa/PCl = 2.2).
