Figure. Concentration-dependent activation of CCR10 by CCL27. Reporter cells were transfected with either the expression plasmid for C-C motif chemo­kine receptor 10 (CCR10) or the mock plasmid and treated with various concentrations of C-C motif chemo­kine ligand 27 (CCL27). 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 27 nM.
