The non-phospho-CB2 receptor antibody is directed against the distal end of the carboxyl-terminal tail of human CB2. It can be used to detect total CB2 receptors in Western blots independent of phosphorylation. The CB2 antibody can also be used to isolate and enrich CB2 receptors from tissue lysates. It also detects CB2 in cultured cells and tissue sections by immunohistochemistry.

Figure 1. Agonist-induced Serine425 phosphorylation of the Cannabinoid Receptor 1. Upper panel, HEK293 cells stably expressing the CB1-Receptor (CB1) were either not exposed or exposed to 10 µM of CB1-Receptor agonists CP55940 for 30 minutes. Cells were lysed and immunoblotted with the anti-pS425-CB1 antibody (7TM0056A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-CB1 antibody to confirm equal loading of the gel.
