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 six putative 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-termini of all TRPs are intracellular3.
According to IUPHAR, the TRP family is comprised of numerous subfamilies on the basis of sequence homology; TRPC, TRPM, TRPV, TRPA, TRPML, and TRPP1-4. The TRPV subfamily consists of six members, TRPV1-65.
Four members of the TRPV family have been described as thermosensitive ion channels (TRPV1 to TRPV4). Each channel exhibits distinct thermal activation thresholds ranging from noxious cold (<17°C) to noxious heat (>52°C) 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 ~52°C and is considered to play an essential role in the perception of high-intensity noxious heat stimulation8-10. TRPV2 is also considered to be a stretch-activated channel and to play a role in skeletal and cardiac muscle degeneration and pain pathway8. The TRPV2 channel is expressed in DRG neurons, different brain regions and non-neuronal tissues such as the spleen, lung and intestine and in components of the immune system5,11,12.

Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of rat TRPV2. Guinea pig Anti-TRPV2 (VRL1) (extracellular) Antibody (#AGP-033) raised in guinea pigs, can be used in western blot and immunocytochemistry. It has been designed to recognize TRPV2 from mouse and rat samples. The antigen used to immunize guinea pigs is the same as Anti-TRPV2 (VRL1) (extracellular) Antibody (#ACC-039) raised in rabbit. Our line of guinea pig antibodies enables more flexibility with our products such as multiplex staining studies, immunoprecipitation, etc.
- Anti-TRPV2 (VRL1) Antibody (#ACC-032). This antibody recognizes a different epitope and thus can also be used as a control for detecting TRPV2.
- Anti-TRPV2 (VRL1) (extracellular)-FITC Antibody (#ACC-039-F). This FITC-conjugated antibody can be used to detect TRPV2 in live cell flow cytometry.
- Anti-TRPV2 (VRL1) (extracellular) Antibody (#ACC-039). This antibody recognizes an extracellular epitope and can be used to detect TRPV2 in live cells. This antibody has been raised against the same epitope as #AGP-033.
- Anti-TRPV2 (VRL1) (extracellular)-FITC Antibody (#ACC-039-F). A fluorescent labeled primary antibody. It can be used to detect TRPV2 in live cells.
