TABLE 3.

Relative conductances in NaCl, LiCl, and CsCl solutions at V_m = −40 mV for WT GlyR channels at 22°C

NaCl(1)	LiCl	CsCl	NaCl(2)	n
1.01 ± 0.01	0.93 ± 0.01	1.04 ± 0.01	0.99 ± 0.01	5

Each value gives the averaged slope conductance from −35 mV to −45 mV (relative to the average NaCl (1) and NaCl (2) values) in each solution for n experiments. For each experiment, the measurements were done on the same cell, starting with NaCl [NaCl(1)], then going sequentially to LiCl, to CsCl, and back to NaCl [NaCl(2)]. V_m was corrected for liquid junction potentials before the conductances were measured.
