Application(s)ELISA, IHC-Frozen
Antibody HostRabbit
Antibody TypePolyclonal
SpecificitySpecificity was demonstrated by immunohistochemistry. When used for immunohistochemistry in rat dorsal root ganglia, staining is restricted to the known distribution of TrkA, that is in small, nociceptive neurons. Reacts with human, rat and mouse TrkA. Other species not yet tested.
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionExtracellular domain of glycosylated human TrkA protein produced in mammalian cells was used as the immunogen.

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 of TrkA receptor in human neuroblastoma SH-SY5Y cell lysate (30 µg/lane). R-152-100 detects TrkA full-length protein at 130-140 kDa under non-reducing conditions (no DTT or beta-mercaptoethanol!). Higher molecular-weight bands may represent homodimeric forms of TrkA or heterodimeric TrkA-receptor complexes. The identity of lower molecular weight bands is unknown. SDS-PAGE: denatured and non-reducing; Transfer: Tris-Glycine buffer; Membrane: nitrocellulose (0.45 um); Blocking: 5% skim milk in TBST, 1 hour at RT; Primary antibody: overnight at 4°C (1/2500 dilution); Secondary antibody: anti-rabbit-HRP (1/6000) 2 hours at RT; Detection: Chemiluminiscence. Predicted MW of humanTrkA based on amino acid sequence: 84 kDa. The observed MW differs due to post-translational modification, mainly glycosylation.
