CA200656 CellAura fluorescent β2 antagonist [(±)-propranolol]: Scientist Approved

Biological Data

Application notes For imaging at β1 / β2 / β3 adrenoceptors use solutions up to 100 nM.
Pharmacological validation The CellAura fluorescent β2 antagonist [(±)-propranolol] ligand was shown to antagonize the activity of the non-selective β agonist, isoprenaline, in three separate recombinant CHO cell lines expressing either the human β1, β2 or β3 receptor and a cyclic AMP-responsive secreted placental alkaline phosphatase (SPAP) reporter gene. To determine the apparent KD for CellAura fluorescent β2 antagonist [(±)-propranolol] at β1, β2 and β3 receptors, cells were treated with varying concentrations of isoprenaline alone, or in the presence of 1µM CellAura fluorescent β2 antagonist [(±)-propranolol], and the cyclic AMP-induced expression of SPAP measured.The apparent KD was calculated from the rightward shift of the agonist response curve in the presence of CellAura fluorescent β2 antagonist [(±)-propranolol], compared to the response curve for the agonist alone, for β1, β2 and β3 receptor expressing cell lines. The ACS β2 adrenoceptor CHO-K1 cell line was also transfected with the cAMP-responsive SPAP reporter construct and tested for its functional response to varying concentrations of isoprenaline alone, or in the presence of 1µM CellAura fluorescent β2 antagonist [(±)-propranolol].
