Background: Adenosine A1 receptor (ADORA1 or RDC7) is a G protein- coupled receptor for adenosine. RT-PCR detected A1 expression in the brain, colon, jejunum, ileum and kidney. A1 functions in sleep-wake regulation, the fertilization process, and modulates coronary blood flow.
Application: Functional assays

Dose-dependent inhibition of forskolin-stimulated intracellular cAMP accumulation 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.
