Detection of Cannabinoid R2/CB2/CNR2 in HEK293 Human Cell Line Transfected with Human Cannabinoid R2/CB2/CNR2 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with either (A) human Cannabinoid R2/CB2/CNR2 or (B) irrelevant transfectants and eGFP was stained with Mouse Anti-Human Cannabinoid R2/CB2/CNR2 Monoclonal Antibody (Catalog # MAB36551R) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). Quadrant markers were set based on control antibody staining (Catalog # MAB0041). View our protocol for Staining Membrane-associated Proteins.

Background: Cannabinoid R2/CB2/CNR2

Cannabinoid R2 (Cannabinoid Receptor 2), also called CB2 or CNR2, is a 7TM protein that belongs to the family of G protein-coupled receptors, class A. Cannabinoid R2 is expressed in the periphery, notably by hematopoietic cells, in contrast to Cannabinoid R1 which is expressed predominantly in the central nervous system and gut. Cannabinoid R2 on lymphocytes and macrophages binds cannabinoids and modulates cytokine secretion. With the exception of their divergent C‑terminal tails, human Cannabinoid R2 shares 82% amino acid sequence identity with mouse and rat Cannabinoid R2.
