Clone 2J4 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects TrkA . It targets an epitope within 21 amino acids from the C-terminal, cytoplasmic domain.

High affinity nerve growth factor receptor (UniProt: P04629; also known as EC:2.7.10.1, Neurotrophic tyrosine kinase receptor type 1, TRK1-transforming tyrosine kinase protein, Tropomyosin-related kinase A, Tyrosine kinase receptor, Tyrosine kinase receptor A, Trk-A, gp140trk, p140-TrkA) is encoded by the NTRK1 (also known as MTC, TRK, TRKA) gene (Gene ID: 4914) in human. TrkA is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-32), which is subsequently cleaved off to produce the mature protein that contains an extracellular domain (aa 33-423), a transmembrane domain (aa 424-439), and a cytoplasmic domain (aa 440-796). The extracellular domain of Trk-A is composed by five domains: a leucine-rich region, two cysteine-rich domains and two immunoglobulin (Ig)-like domains. TrkA serves as a receptor tyrosine kinase involved in the development and the maturation of the central and peripheral nervous system through regulation of proliferation, differentiation, and survival of sympathetic and nervous neurons. It serves as a high affinity receptor for NGF, which is its primary ligand. It can also bind and be activated by neurotrophin-3 (NTF3). However, NTF3 only supports axonal extension through NTRK1 but does not affect neuron survival. Upon dimeric NGF ligand-binding, it undergoes homodimerization, autophosphorylation. and activation. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

KLH-conjugated linear peptide corresponding to 21 amino acids from the C-terminal, cytoplasmic domain of human TrkA.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
