Genbank #: P20783
a.a: 139–257
Background: NT-3 is found in neurons of the central nervous system. NT-3 is expressed also in muscles and its expression is down-regulated in denervated muscles. Many human gliomas express and secrete NT-3 into the conditioned medium. Some protein domains of NT-3 are identical with those of NGF and BDNF. NT-3 selectively supports the survival of neuronal cell populations, and prevents the death of cultured embryonic rat spinal motor neurons at picomolar concentrations. NT-3 has been shown to enhance sprouting of corticospinal tract during development and after adult spinal cord lesion. The activities of NT-3 and BDNF are additive in some systems. The biological activities of NT- 3 are mediated by a receptor belonging to the trk family of receptors with intrinsic tyrosine-specific protein kinase activity. NT-3 only binds weakly to the trk receptor which is a high-affinity receptor for NGF.
UniProt P20783
Synonym(s): NT3, Neurotrophin 3, NT-3, NGF-2, Nerve Growth Factor 2, NTF3
Purity: ≥97% by SDS-PAGE and HPLC
Endotoxin Level: <0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity: The ED50 was determined by the dose-dependent induction of choline acetyl transferase activity in rat basal forebrain primary septal cell cultures was found to be in the range of 10-50 ng/ml.
Formulation: Lyophilized from a 0.2 µm filtered PBS solution, pH 7.5.
Format: lyophilized protein
Reconstitution: Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability: The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles. Reference(s): 1.
