Overview
Anti-TRPA1 (extracellular) Antibody is an antibody targeting Transient receptor potential cation channel subfamily A member 1, ANKTM1, Ankyrin-like with transmembrane domains protein 1, Transformation-sensitive protein p120 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IFC, IHC, IP, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Transient receptor potential cation channel subfamily A member 1, ANKTM1, Ankyrin-like with transmembrane domains protein 1, Transformation-sensitive protein p120 (also reported as Transient receptor potential cation channel subfamily A member 1, ANKTM1, Ankyrin-like with transmembrane domains protein 1, Transformation-sensitive protein p120).
- Immunogen/epitope region: 1st extracellular loop.
- Homology note: Bovine - identical; canis - 13/14 amino acid residues identical; rat - 12/14 amino acid residues identical; mouse - 9/14 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Cited use: IP, IHC, ICC, IFC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
The TRPA family is comprised of only one mammalian member, the TRPA1 (formerly named ANKTM1). TRPA1 is expressed in peripheral sensory neurons, where it is suggested to contribute to the detection of painful stimuli.1Originally, it was thought that TRPA channels sensed painfully cold temperatures,2 but a more conservative description is that TRPA1 is sensitive to membrane/cytoskeletal perturbations caused by low temperatures3-5 and perhaps stretch.6 In addition, it is sensitive to pungent natural compounds present in cinnamon oil, mustard oil, and wintergreen oil.TRPA1 is also expressed in hair cells, where its role in sensing mechanical forces is still unclear and controversial.1TRPA1 has a similar structure to all other TRP ion channels; six transmembrane domains, intracellular N-and C-terminus. However, the N-terminal domain possesses 17 ankyrin repeats that might indicate its potential role as a mechanosensor.6,7In addition, TRPA1 is expressed in nociceptive neurons expressing TRPV1 and might serve as a marker for polymodal nociceptors.8
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
- Immunoprecipitation (IP): enrich the target for downstream detection or complex analysis (context-dependent).
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: BLP-CC037.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
