SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen.
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionA synthetic peptide corresponding to a sequence in the middle region of human TrkA (342-361aa) RHGCLRLNQPTHVNNGNYTL). This sequence is identical to the related rat and mouse sequences as well.
Application DetailsWestern Blotting (WB). A concentration of 0.1-0.5 µg/mL is recommended for WB. A concentration of 0.5-1.0 µg/mL is recommended to detect the protein in formalin fixed and paraffin embedded tissues. Heat mediated antigen retrieval is recommended. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundTrkA is a member of the neurotrophic tyrosine kinase receptor family. It is a membrane-bound receptor that upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. TrkA is required for high-affinity binding to nerve growth factor (NGF), neurotrophin-3 and neurotrophin-4/5 but not brain-derived neurotrophic factor (BDNF). TrkA leads to cell differentiations and may play a role in specifying sensory neuron subtypes. It has a crucial role in the development and function of the nociceptive reception system as well as establishment of thermal regulation via sweating. SUBUNIT: Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. SUBCELLULAR LOCATION: Cell membrane; single-pass type I membrane protein. Endocytosed to the endosomes upon treatment of cells with NGF. ALTERNATIVE PRODUCTS: 2 named isoforms produced by alternative splicing. Both isoforms have similar biological properties. TISSUE SPECIFICITY: Isoform TrkA-II is primarily expressed in neuronal cells. Isoform TrkA-I is found in non-neuronal tissues. Mutations in TrkA have been associated with congenital insensitivity to pain, anhidrosis, self-mutalating behaviour, mental retardation and cancer.
Western blot analysis of TrkA expression in rodent RIPA cell lysates and tissue homogenates under reducing (A) and non-reducing conditions (B.). TrkA antibody R-1362-100 detects both gp140TrkA and gp110TrkA isoforms under reducing and non-reducing conditions.. Additional uncharacterized bands at lower molecular weights are observed. SDS-PAGE: 4-12%; Transfer: Tris-Glycine buffer; Membrane: PVDF (0.45 μm); Blocking: 5% skim milk in TBST, 1.5 hour at RT; Primary antibody overnight at 2-8°C (0.5 μg/mL); Secondary antibody: anti-rabbit-HRP (1:6,000) 2 hours at RT; Detection: Chemiluminiscence.
