Solubilize for 30 minutes at room temperature with occasional gentle vortexing. Carrier free: Add sterile PBS, or PBS containing protein to minimize absorption of hNT-3 to surfaces. Solubilize for 30 minutes at room temperature with occasional gentle vortexing. Stock hNT-3 should be greater than 50 μg\/ml.\n\u003cb\u003eFormulation\u003c\/b\u003e\nWith carrier: Lyophilized from a 0.22 μm filtered solution of 20 mM phosphate, pH 8.0 containing 500 mM NaCl and 20 μg BSA per 1 μg hNT-3. Carrier free: Lyophilized from a 0.22 μm filtered solution of 20 mM phosphate, pH 8.0 containing 500 mM NaCl.\n\u003cb\u003eStorage\u003c\/b\u003e\nStable in lyophilized state at -20°C for 24 months after receipt. Sterile stock solutions reconstituted with carrier protein are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles. Maintain sterility. Storage at -20°C should be in a manual defrost freezer.\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nRecombinant human Neurotrophin-3 (hNT-3) Tyr139-Thr257 (Accession #NP_002518) was produced in at Cell Signaling Technology.\n\u003cb\u003eBackground\u003c\/b\u003e\nNT-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).","brand":"CST","offers":[{"title":"Default Title","offer_id":46800714629289,"sku":"5237SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-5237sf","provider":"Iright","version":"1.0","type":"link"}
