TRPV1 Polyclonal Antibody, Invitrogen™

Description

PA1-29421 detects Vanilloid receptor 1 from rat, human, mouse, and non-human primate samples. PA1-29421 has been successfully used in immunocytochemistry, immunohistochemistry (frozen tissue), and Western blot applications. A suggested positive control for this product is VR1 transfected cells. Predicted molecular weight of approximately 100.7 kDa. The PA1-29421 immunogen is synthetic peptide, RASLDSEESESPPQENSC, corresponding to amino-terminus of Rat VR1, amino acids 4-21. Store product as a concentrated solution. Centrifuge briefly prior to opening the vial. For short-term storage (1-2 weeks), product can be stored at 4°C. For long-term storage, aliquot and store product at -20° C or below, avioiding multiple freeze-thaw cycles.

TRPV1 (Transient Receptor Potential Cation Channel Subfamily V Member 1) is a receptor for capsaicin, the main pungent ingredient in hot chili peppers, and elicits a sensation of burning pain by selectively activating sensory neurons. TRPV1 is a non-selective cation channel that is structurally related to members of the TRP family of ion channels such as TRPC3 and TRPC6. TRPV1 is permeable to calcium, magnesium, and monovalent cations of sodium and potassium. Structurally, TRPV1 contains 6 trans-membrane domains, a P-loop membrane domain and 3 ankyrin repeat domains. TRPV1 is also activated by increases in temperature in the noxious range, suggesting that it functions as a transducer of painful thermal stimuli in vivo. TRPV1 seems to mediate proton influx and may be involved in intracellular acidosis in nociceptive neurons. The expression of TRPV1 appears to be limited to neurons within the sensory ganglia. Four transcript variants encoding TRPV1 with variations in th 5′ UTR sequence have been described. Diseases associated with TRPV1 include Irritable Bowel Syndrome (IBS) and Bladder Disease.
