Data Sheet
Background: Cannabinoid Receptor 1, CNR1 also known as CB1, is primarily involved in cannabinoid induced CNS effects. It acts by inhibiting intracellular adenylate cyclase activity and could be a receptor for anandamide. CB1 receptor is found in both central and peripheral tissues an recently, this receptor is also emerging as a potential therapeutic target for obesity-related diseases. It has two Isoforms CB1a and CB1b, CB1b is formed by internal deletion of 33 amino acids and preferentially expressed in B cells and Hepatocyte of Liver and is a more powerful modulator of adenyl cyclase activity.
Application: Functional assays
Figure 1. Dose-dependent stimulation from arrestin recruitment upon treatment with ligand, measured with MultiScreenTM β-Arrestin Assay Kit (Multispan MSBA01). Figure 2. 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.
