General description

NT-3 (neurotrophin 3) is a neurotrophic factor structurally related to β-NGF (nerve growth factor), BDNF (brain-derived neurotrophic factor), and NT-4. These proteins belong to the cysteine-knot family of growth factors that assume stable dimeric structures. NT-3 is expressed by neurons of the central nervous systems and can signal through the trk receptors. Recombinant human NT-3 is a noncovalently linked homodimer, of two 13.6kDa polypeptide monomers (240 total amino acid residues). The amino acid sequences of human, murine and rat NT-3 are identical.

Biochem/physiol Actions

NT-3 (neurotrophin 3) promotes the growth and survival of nerve and glial cells. It is associated with neuroprotection and polymorphisms in the gene are associated with risk to Alzheimer′s disease. It is also linked with attention-deficit/hyperactivity disorder (ADHD) and mood disorders. NT-3 enhances the metastatic proliferation of breast cancer cells in the brain.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
