Pharmacological characterization of GLIC/GlyR chimera. (a) Proton response curves for GLIC (blue) and chimera (purple) receptors. Dashes indicate EC10, ~pH 7.25 for the chimera. (b) Potentiation of chimera receptors by various concentrations of ethanol, measured as in Fig. 1, in the presence (lavender) and absence (purple) of 10 mM tricine to chelate environmental zinc. Tricine did not alter ethanol responses at any concentration tested. In a–b, errors are s.e.m., n = 2–7.
