TrkB (TrkB tyrosine kinase, Trk-B) (pTyr816) antibody

Antigen: TrkB (TrkB tyrosine kinase, Trk-B)

Binding Site: pTyr816

Clonality: Polyclonal

Host: Rabbit

Application: Immunohistochemistry (IHC), Western Blotting (WB)

Catalog no.: ABIN351083

Additional Information

UniProt: Q16620

Immunogen: A synthetic peptide from the region around (and including) phospho Y816 site of human TrkB (BDNF/NT-3 growth factors receptor, TrkB tyrosine kinase, Trk-B) conjugated to an immunogenic carrier protein was used as the immunogen. The antigen is homologous in rat and mouse.

Format: Lyophilized

Description: FUNCTION: Receptor for brain-derived neurotrophic factor (BDNF), neurotrophin-3 and neurotrophin-4/5 but not nerve growth factor (NGF). Involved in the development and/or maintenance of the nervous system. This is a tyrosine-protein kinase receptor. Known substrates for the TRK receptors are SHC1, PI-3 kinase, and PLC-gamma-1. CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. SUBUNIT: Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. Binds SH2B2. Interacts with SQSTM1 and ARMS. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. Also known as: Neurotrophic tyrosine kinase receptor type 2, TrkB tyrosine kinase, GP145-TrkB/GP95-TrkB, Trk-B, BDNF/NT-3 growth factors receptor.

Specificity: Appears to be specific for TrkB.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 2000 is recommended. The optimal dilution should be determined by the end user. This antibody is also likely to recognise the unphosphorylated form.

Purity: whole serum

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
