The Bioaim Rat beta-NGF ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of beta-NGF in rat serum, plasma and cell culture media. An antibody specific for rat beta-NGF was coated on a 96-well plate. Standards and samples are added to the wells and any beta-NGF present binds to the immobilized antibody. The wells are washed and biotinylated anti-rat beta-NGF antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of beta-NGF present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Apoptosis, Cell growth and differentiation;
nerve growth factor( β-NGF ) Background: 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. As its name suggests, NGF is involved primarily in the growth, as well as the maintenance, proliferation, and survival of nerve cells (neurons). In fact, NGF is critical for the survival and maintenance of sympathetic and sensory neurons, as they undergo apoptosis in its absence. However, several recent studies suggest that NGF is also involved in pathways besides those regulating the life cycle of neurons. NGF binds with at least two classes of receptors: the tropomyosine receptor kinase A (TrkA) and low-affinity NGF receptor (LNGFR/p75NTR). Both are associated with neurodegenerative disorders. When NGF binds to the TrkA receptor, it drives the homodimerization of the receptor, which in turn causes the autophosphorylation of the tyrosine kinase segment. This leads to the activation of PI 3-kinase, ras, and PLC signaling pathways. Alternatively, the p75NTR receptor can form a heterodimer with TrkA, which has higher affinity and specificity for NGF.
