Beta-NGF Recombinant Protein

Human beta -Nerve Growth Factor (beta -NGF) was initially isolated in the mouse submandibular gland. It is composed of three non-covalently linked subunits alpha, beta , and gamma ; it exhibits all the biological activities ascribed to NGF. It is structurally related to BDNF, NT-3 and NT-4 and belongs to the cysteine-knot family of growth factors that assume stable dimeric structures. beta -NGF is a neurotrophic factor that signals through its receptor beta -NGF, 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. These results suggest that beta -NGF is a pleiotropic cytokine, which in addition to its neurotropic activities may have an important role in the regulation of the immune system. Human beta -NGF shares 90% sequence similarity with mouse protein and shows cross-species reactivity.

Lyophilized from a 0.2 um filtered solution of 20mM PB, 250mM NaCl, pH 7.0. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in ddH2O.
