Data Sheet

Background: Adrenergic α2a receptor belongs to the group of nine adrenoceptors that mediate the biological actions of adrenaline and noradrenaline. The α2a receptor is expressed in the brain, spleen, kidney, heart and gastrointestinal tract. It is centrally predominant and exerts a tonic sympathoinhibitory function, whereas peripherally it has a vasoconstrictive effect. The α2a receptor is also involved in sedation, digestive functions and analgesia.

Application: Functional assays

Dose-dependent inhibition of forskolin-stimulated intracellular cAMP level upon treatment with ligand, measured with MultiscreenTM TR-FRET cAMP 1.0 No Wash Assay Kit (Multispan MSCM01). 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.
