General description
TrkA, apparent molecular weight 140 kDa, is a high affinity nerve growth factor (NGF). The Trk proto-oncogene family contains four members, TrkA, TrkB, TrkC, and TrkE, which are variably expressed throughout the central and peripheral nervous systems. TrkA binds to nerve growth factor (NGF) and autophosphorylates on tyrosine residues (Tyr490, Tyr674, Tyr675, Tyr751 and Tyr785) to activate multiple downstream effector proteins. Phosphorylation at Tyr490 is required for Shc association and subsequent activation of the Ras-MAP kinase-signaling cascade, which leads to activation of Elk-1-dependent gene transcription and neurite growth. Phosphorylations at Tyr674 and Tyr675 lie within the catalytic domain of TrkA tyrosine kinase and reflect Trk kinase activity. Additionally, phosphorylation at Tyr751 is required for PI3-kinase association and activation of the Akt signaling cascade.
Specificity
Reactivity with other species has not been confirmed.
Recognizes TrkA, Mr 140 kDa. Does not cross-react with TrkB or TrkC.
Immunogen
Rabbits immunized with bacterially expressed purified protein corresponding to the entire extracellular domain of rat TrkA receptor.
Application
Anti-TrkA Antibody detects level of TrkA & has been published & validated for use in IC, IP & WB.
Immunoprecipitation:
4 μg of a previous lot immunoprecipitated TrkA from 500 μg of PC-12 RIPA lysate.
Immunocytochemistry:

Physical form
Format: Purified
Protein A purified
Purified rabbit IgG in buffer containing 0.02 M phosphate buffer, pH 7.6, 0.25 M NaCl, 0.1% sodium azide. Frozen at -20°C.
Storage and Stability
Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerolcontaining solutions to become frozen during storage.
