Specifications

beta-NGF is a neurotrophic factor structurally related to BDNF, NT-3 and NT-4.These proteins belong to the cysteine-knot family of growth factors that assume stable dimeric structures.beta-NGF is a potent neurotrophic factor that signals through its receptor beta-NGFR, and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems.beta-NGF also acts as a growth and differentiation factor for B lymphocytes and enhances B-cell survival.The functional form of human beta-NGF is a noncovalently disulfide-linked homodimer, of two 13.5kD polypeptide monomers (240 total amino acid residues).The three disulfide bonds are required for biological activity.

Storage and StabilityStore lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein.
