Description
Figure. Concentration-dependent activation of GRM1 by L-glutamic acid. Reporter cells were transfected with either the expression plasmid for glutamate metabotropic receptor 1 (GRM1) or the mock plasmid and treated with various concentrations of L-glutamic acid. Data points shown are the mean ± SEM of an experiment performed in triplicate, and the curve is a fit to Hill equation with an EC50 of 6.4 µM.
