Extra Details:: 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 murine Beta-NGF is a noncovalently disulfide-linked homodimer, of two 13.4kD polypeptide monomers (240aa). The three disulfide bonds are required for biological activity. Source: Recombinant protein corresponding to mouse NGF beta, expressed in E.coli. Biological Activity: Determined by the dose-dependent stimulation of the proliferation of human TF-1 cells. The ED50 was found to be <1ng/ml. Sspecific Activity: 1x10e6units/mg Endotoxin: <0.1ng/ug (1EU/ug) AA Sequence: MSSTHPVFHM GEFSVCDSVS VWVGDKTTAT DIKGKEVTVL AEVNINNSVF RQYFFETKCR ASNPVESGCR GIDSKHWNSY CTTTHTFVKA LTTDEKQAAW RFIRIDTACV CVLSRKATRR G Storage and Stability: May be stored at 4°C for short-term only.
