Background

NT-3 is a member of the structurally related neurotrophin family of proteins, which includes β-NGF, BDNF and NT-4 (1). NT-3 is expressed in a number of cell types including neuronal cells, eosinophils, and melanocytes (1-3). NT-3 is required for the development of peripheral sensory neurons (4). NT-3 is secreted from cells as a precursor protein, which is proteolytically cleaved into the mature form (1). NT-3 signaling is mediated through two distinct receptors, the neurotrophin receptor p75NTR and the Trk tyrosine kinase receptor TrkC. While all neurotrophins bind to the p75NTR receptor, NT-3 preferentially binds to TrkC and, with lesser affinity, TrkB (1).

Endotoxin

Less than 0.01 ng endotoxin/1 μg hNT-3.

Purity

>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hNT-3. All lots are greater than 98% pure.

Source / Purification

Recombinant human Neurotrophin-3 (hNT-3) Tyr139-Thr257 (Accession #NP_002518) was produced in E.coli at Cell Signaling Technology.

Bioactivity

The bioactivity of recombinant hNT-3 was determined in a TrkC-transfected NIH/3T3 cell proliferation assay. The ED50 of each lot is between 0.5 - 5 ng/ml.

The ability of hNT-3 to induce phosphorylation of TrkB was assessed. After starvation, TrkB-transfected NIH/3T3 cells were treated with increasing concentrations of hNT-3 for 5 minutes. Cells were lysed, and phospho-TrkB was quatified using PathScan® Phospho-TrkB (panTyr) Sandwhich ELISA Kit #7108. OD450-OD650 is shown.

The proliferation of TrkC-transfected NIH/3T3 cells treated with increasing concentrations of hNT-3 was assessed. After 24 hr treatment, cells were labeled with BrdU for 4 hrs. BrdU incorporation was determined by ELISA and the OD450-OD690 was determined.

The purity of recombinant hNT-3 was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant hNT-3 and staining overnight with Coomassie Blue.
