³H-cAMP accumulation in response to cimaterol in (a) CHO β₁ cells, (b) CHO β₂ cells, and (c) CHO β₃ cells in the absence and presence of 19. Bars show basal ³H-cAMP accumulation, that in response to 10 μM isoprenaline, and that in response to 30 nM, 100 nM, 300 nM, 1 μM, 3 μM, and 10 μM 19 alone. Data points are the mean ± SEM of triplicate values from single experiments that are representative of seven separate experiments in each case.
