Applications:

Western Blotting:

Western blotting of  ND7/23 cell line membrane (1,3), RBL lysates (2,4)  and rat brain membrane (5,6): 1,2,5. Anti-TRPV2 (extracellular) antibody, 1:200. 3,4,6. Anti-TRPV2 (extracellular) antibody, preincubated with the control peptide antigen.

Immunocytochemistry:

Immunocytochemical staining of rat basophilic leukemia cells (RBL) with Anti-TRPV2 (extracellular) antibody. Cells were incubated with Anti-TRPV2 (extracellular) antibody (#ACC-039) (1:100), followed by goat-anti-rabbit-Alexa fluor-550 (red) (x100).

Immunoprecipitation:

Immunoprecipitation of rat basophilic leukemia (RBL) lysate: 1. RBL lysate. 2. RBL lysate immunoprecipitated with Anti-TRPV2 (extracellular) antibody (#ACC-039) (6 mg). 3. RBL lysate immunoprecipitated with pre-immune rabbit serum. The upper arrow indicates the TRPV2 channel while the lower arrow indicates the IgG heavy chain. Western blotting was performed with Anti-TRPV2 (extracellular) antibody.

TRP channels are a large family (about 28 genes) of plasma membrane, non-selective cationic channels that are either specifically or ubiquitously expressed in excitable and non-excitable cells.¹ The TRP channels have putative six-transmembrane domains (TM) with a pore domain between the fifth and the sixth TM, and all assemble as tetramers. Both the N- and the C-terminus of all TRPs are intracellular.³

According to IUPHAR, the TRP family is comprised of three main subfamilies on the basis of sequence homology; TRPC, TRPM and TRPV (to date, three additional subfamilies are also considered to belong to the TRP family: the TRPA, TRPML, and TRPP).^1-4 The TRPV subfamily consists of six members, TRPV1-6.⁵

Four members of the TRPV family have been described as a thermosensitive ion channels (TRPV1 to TRPV4). Each channel exhibits distinct thermal activation thresholds ranging from noxious cold (<17èš“) to noxious heat (>52èš“).^6,7 Although it shares around 50% homology with TRPV1, TRPV2 is not activated by capsaicin nor by protons. It has a high temperature threshold of ~52èš“ and is considered to play an essential role in the perception of high-intensity noxious heat stimulation.^8-10 The TRPV2 is also considered to be a stretch-activated channel and to play a role in skeletal and cardiac muscle degeneration and pain pathway.⁸ TRPV2 channel is expressed in DRG neurons, different brain region and non-neuronal tissues such as spleen, lung and, intestine and in component of the immune system.^5,11-12

Alomone Labs is pleased to release two novel antibodies to both intracellular TRPV2 and extracellular TRPV2, Anti-TRPV2 (#ACC-032) and Anti-TRPV2 (extracellular) (#ACC-039), respectively.
