TRPA1 (transient receptor potential cation channel subfamily A member 1; originally named as ANKTM1) is a member of transient receptor potential ion channels (TRPCs) which responds to stimuli such as cold temperatures, pungent compounds, and plays role in both nociceptor and hair cell transductions. TRPA1 is activated by variety of mechanical and chemicals stimuli including dietary irritants such as isothyocyanates (found in mustard oil, horse-radish, wasabi), allycin/garlic etc. and its activity is regulated by endogenous pro-inflammatory factors such as cyclopentane prostaglandins and byproducts of oxidative stress (e.g. 4-HNE, 4-oxononenal) which activate TRPA1 directly via covalent modification of its cysteine residues. Once TRPA1 is activated, increased intracellular Ca2+ induces the peripheral release of neuropeptides namely substance P and CGRP (calcitonin gene-related peptide), purines, and other transmitters from sensitized nerve endings, which results in neurogenic inflammation and hypersensitivity. TRPA1 is mainly expressed in small-diameter peptidergic nociceptors of the dorsal root, nodose and trigeminal ganglia, along with TRPV1, and has also been reported to be expressed in non-neuronal tissues (skeletal muscle, lung, small intestine, colon, pancreas etc) and is found dysregulated during process of carcinogenesis in certain malignancies.

FAQs for TRPA1 Antibody (NB110-40763). (Showing 1 - 4 of 4 FAQs).
I read the first publication (Yu S et al. 2009) referenced for NB110-40763. This product reacts with human and mouse according to your datasheet, but in that publication it was used for western blot in guinea pig. Does this mean this antibody is suitable to use for guinea pig samples?
Yes, according to this paper this antibody has been successfully used on guinea pig samples. This is the only testing that has been done in guinea pig though as we have done no in-house testing. It should work just fine for you.
Has the specificity of NB110-40763 has been confirmed by mouse dorsal root ganglion (DRG) tissue in immunohistochemistry? Do you know what sample types have been tested?
We have a couple of publications with the base product catalog number NB110-40763 (which is just the unconjugated version of NB110-40763G), which have utilized our product with mouse colonic dorsal root ganglion. (PMID 19875705 and PMID 21689654). The image on our website was taken of a mouse intestine sample.
What are the other two bands in the image on the datasheet? UniProt finds a theoretical MW of 127.5kDa. You find a MW of 110kDa in WB application. There are two more bands at 60kDa and 17kDa. What are these? Unspecific staining or fragments or variants of the protein? I did not find any info on variants when looking into the UniProt data (http://www.uniprot.org/uniprot/O75762).
We generally use gradient gels in our lab and for proteins which are multi-pass membrane protein, it is not uncommon to see an approximate 10-15% change in expected vs observed molecular weight in WB assay. The band observed at approximately 110kD is highly specific and there is no doubt that the antibody is detecting the right band. No, we have not characterized the additional low molecular weight bands yet which are considerably mild bands when compared to the expected target band. During a brief literature research this morning, I came across some papers wherein other researchers have also observed additional lower molecular weight bands and some of those references are: J Biol Chem. 2010 May 14; 285(20): 15167-15177; J Biol Chem. 2006 October 27; 281(43): 32879-32890; J Clin Invest. 2007 July 2; 117(7): 1979-1987.
Human brain membrane fraction is mentioned to be used as a positive control for this antibody. Do you sell the positive control too?
The Western blot data that is shown on our product page for the TRPA1 antibody with catalogue number NB110-40763 was, as you have pointed out, generated from human brain membrane lysate. We do sell a human brain membrane fraction that is suitable for Western blotting, and you can see this here: TRPA1 antibody datasheet. This lysate is supplied as native protein, and we recommend adding 1 x sample buffer with 5% BME (or other reducing agent) prior to use.
