Figure. Concentration-dependent activation of FPR2 by WKYMVM. Reporter cells were transfected with either the expression plasmid for formyl pep­tide receptor 2 (FPR2) or the mock plasmid and treated with various concentrations of WKYMVM. 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 940 pM.
