Cannabinoid receptor CB₁ polyclonal antibody

The cannabinoid receptors CB1 and CB2 are GPCRs named for their signaling function in response to cannabinoid drugs such as Delta9-tetrahydrocannabinol (Delta9-THC). In addition to Delta9-THC and its synthetic analogs, CB1 and CB2 receptors are bound by endogenous eicosanoid ligands (e.g. anandamide), and signal via Gi/o alpha subunits to regulate adenylyl cyclase activity (generally inhibitory), ion channel activation, intracellular Ca2+ levels, nitric oxide synthase activation, and immediate early gene expression. CB1 and CB2 signals in turn regulate neurological and immunological functions such as inhibition of neurotransmitter release and immune cell migration, antigen processing, and cytokine production.
