Data Examples

Western Blot Detection of Rat TrkA by Western Blot. View Larger

Detection of Rat TrkA by Western Blot. Western blot shows lysate of rat striatum tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Rat TrkA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1056) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for TrkA at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunohistochemistry TrkA in Rat Dorsal Root Ganglion. View Larger

TrkA in Rat Dorsal Root Ganglion. TrkA was detected in perfusion fixed frozen sections of rat dorsal root ganglion using 15 µg/mL Rat TrkA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1056) overnight at 4 °C. Tissue was stained (red). View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background: TrkA

TrkA, the product of the proto-oncogene trk, is a member of the neurotrophic tyrosine kinase receptor family that has three members. TrkA, TrkB, and TrkC preferentially bind NGF, NT-4, and BDNF and NT-3, respectively. All Trk family proteins share a conserved complex subdomain organization consisting of a signal peptide, two cysteine-rich domains, a cluster of three leucine-rich motifs, and two immunoglobulin-like domains in the extracellular region, as well as an intracellular region that contains the tyrosine kinase domain. Two distinct rat TrkA isoforms (TrkA-I and Trk-A-II) that differ by a 6-amino acid insertion in their extracellular domain have been identified. The longer TrkA isoform is the only isoform expressed within neuronal tissues whereas the shorter TrkA-I is expressed mainly in non-neuronal tissues. NGF binds to TrkA with low affinity and activates its cytoplasmic kinase, initiating a signaling cascade that mediates neuronal survival and differentiation. Higher affinity binding of NGF requires the co-expression of TrkA with the p75 NGF receptor (NGF R), a member of the tumor necrosis factor receptor superfamily. NGF R binds all neurotrophins with low affinity and modulates Trk activity as well as alters the specificity of Trk receptors for their ligands. NGF R can also mediate cell death when expressed independent of Trk.
