Background: Norepinephrine is implicated in a wide range of physiological processes through activation of nine different G-protein-coupled receptors (α1a, α1b, α1d, α2a, α2b, α2c, ß1, ß2, ß3). The human ß1-adrenergic receptor is a 477–amino acid protein found in various heart and brain tissues. ß1 has an important role in the contractile action of valves in cardiac and digestive systems.
Application: Functional assays
Figure 1. Dose-dependent stimulation of pERK level upon treatment with ligand, monitored with FlexStation (Cisbio 64AERPEG). Figure 2. Dose-dependent increase of intracellular cAMP level upon treatment with ligand, measured with cAMP HiRange kit (Cisbio 62AM6PEC). Figure 3. Receptor expression on cell surface measured by flow cytometry (FACS) using an anti-FLAG antibody. Thin line: parental cells; thick line: receptor- expressing cells.
