Description
Figure. Concentration-dependent activation of P2RY1 by ADP. Reporter cells were transfected with either the expression plasmid for purinergic receptor P2Y1 (P2RY1) or the mock plasmid and treated with various concentrations of adenosine diphosphate (ADP). 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 3.3 µM.
