Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: TrkB is one of several protein kinases that can phosphorylate KinSub5DDDYV. TrkB is a receptor protein-tyrosine kinase that is a member of the TK group of protein kinases in the Trk family. This kinase shows high variability in human tissue distribution with the highest levels detected in brain, ovary, pancreas, pituitary, spinal cord, thyroid and trachea. TrkB is activated by binding BDNF, NT-3, NT-4 or NT-5, which induce dimerization and autophosphorylation. Phosphorylation at Y516 increases phosphotransferase activity and induces interaction with PLCg1. TrkB activation stimulates signalling throught the MAPK pathway. Signalling through TrkB leads to cell differentiation. Mutations in the TrkB gene have been associated with obesity and mood disorders. TrkB has also been linked with the development of colon and lung cancers, neuroblastomas and pilocytic astrocytomas, which are benign tumours of the brain or spinal cord that grow slowly.
