  • Primary antibody说明Cannabinoids exert their well known physiological effects through two G protein coupled receptors, cannabinoid receptor 1 (CB1) and CB2. Both cannabinoid receptors have been shown to inhibit adenylyl cyclase as well as stimulate the mitogen-activated protein kinase, MAPK. CB1 receptors also modulate ion channels through direct G-protein interactions. Delta 9-tetrahydrocannibinol and related ligands likely exert their psychoactive effects by inhibiting presynaptic N- and P / Q type calcium channels. CB2 is thought to function primarily in the immune system although it has been suggested to be present in the central nervous system, including the retina.

  • 功能Heterotrimeric G protein-coupled receptor for endocannabinoid 2-arachidonoylglycerol mediating inhibition of adenylate cyclase. May function in inflammatory response, nociceptive transmission and bone homeostasis.
  • 组织特异性Preferentially expressed in cells of the immune system with higher expression in B cells and NK cells (at protein level). Expressed in skin in suprabasal layers and hair follicles (at protein level). Highly expressed in tonsil and to a lower extent in spleen, peripheral blood mononuclear cells, and thymus. PubMed:14657172 could not detect expression in normal brain. Expressed in brain by perivascular microglial cells and dorsal root glanglion sensory neurons (at protein level).
  • 序列相似性Belongs to the G-protein coupled receptor 1 family.
  • 翻译后修饰Constitutively phosphorylated on Ser-352; phosphorylation increases cell internalization and desensitizes the receptor.
  • 细胞定位Cell membrane. Cell projection > dendrite. Perikaryon. Localizes to apical dendrite of pyramidal neurons.

  • ab3561 labelling Cannabinoid Receptor II in the cytoplasm of Human tonsil tissue (right) compared with a negative control (left) by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). To expose target proteins, antigen retrieval method was performed using 10mM sodium citrate (pH 6.0) microwaved for 8-15 min. Tissues were blocked in 3% H2O2-methanol for 15 min at room temperature. Tssiue sections were incubated with the primary antibody (1:20 in 3% BSA-PBS) overnight at 4°C. A anti-rabbit HRP was used as the secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

  • ab3561 staining Cannabinoid Receptor II in murine BV2 cells by Immunocytochemistry/ Immunofluorescence. Cells were stimulated with 10 uM ADP for 15 minutes at 37°C, 5%CO2 then washed 3X with PBS and fixed with 2% formaldehyde for 15 minutes at room temperature. A blocking step was performed for 1 hour at room temperature with 5% FBS/PBS/0.01% Triton-X-100. ab3561 used at a 1/500 dilution for 1 hour at room temperature then washed 3X PBS. The secondary was an Alexa Fluor 488 conjugated antibody, used at a 1/250 for 1 hour at room temperature, washed 3X PBS then mounted in Vectashield containing DAPI.
  • Quantification of CB1 and CB2 receptor surface expression in primary Human and HaCaT keratinocytes. (A) FL-1 shows autofluorescence (black population), non-specific binding of secondary antibody (dark grey population) and specific immunofluorescence obtained with CB1 (ab3558) and CB2 (ab3561) receptor antibodies, respectively (light grey population). Histogram shows representative measurement (5000 cells counted). (B) Differences in CB receptor expression between primary and HaCaT keratinocytes, showing marked increased expression of CB2 in primary keratinocytes (geo mean corrected for non-specific binding of secondary Ab). Data show mean values ±SEM obtained with two human primary keratinocyte samples and HaCaT cells, each measured three times.

  • ab3561 at 1/5000 staining Rat spinal cord tissue sections by IHC-P. Following nerve trans-section, the animal was transcardially perfused with PBS followed by 4% formaldehyde (no post fixation) then frozen in OCT and stored at -80°C until required. 20µm sections were cut and stained with the antibody for 18 hours. A biotinylated goat anti-rabbit antibody was used as the secondary.
