Fig. 5. Ion dependency of agNAT8. Representative data from a typical ion
substitution experiment. Different coloured lines represent the response upon
application of 2 mmol l-1 phenylalanine in oocyte medium with
different ion concentrations: yellow, 100 mmol l-1 LiCl; red, 98
mmol l-1 KCl; blue, 98 mmol l-1 sodium gluconate; green,
98 mmol l-1 NaCl. Holding potentials were -50 mV.
