Endotoxin Level: Predicted Molecular Mass:13.2 kDa (monomer) Activity:Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323.The ED₅₀ for this effect is 0.1-0.6 ng/mL. Molecule Information: beta-NGF Long Name: beta Nerve Growth Factor Aliases: NGFB Entrez Gene IDs: 4803 (Human); 18049 (Mouse); 310738 (Rat) Background: beta-NGF Nerve growth factor (NGF) was initially isolated in the mouse submandibular gland over three decades ago as a 7S complex composed of three non- covalently linked subunits, alpha, beta, and gamma. It is now known that both the alpha and gamma subunits of NGF are members of the kallikrein family of serine proteases, while the beta subunit, called beta-NGF or 2.5S NGF, exhibits all the biological activities ascribed to NGF. The human protein shares approximately 90% identity at the amino acid level with both mouse and rat beta-NGF.
