Effects of exogenous PGE2 (added to the bath) on [Ca²⁺]i of an HEK/EP1 biosensor cell. (a) Recordings of five different HEK/EP1 cells demonstrate almost identical sensitivities of cells to 1 μM PGE2. HEK/EP1 [Ca²⁺]i responses were prevented by the coadministration of an EP1 blocker (SC51322). (b) Dose-response curve. Each data point represents the average of four cells studied.
