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. 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.

NGF binds with at least two classes of receptors: the tropomyosine receptor kinase A (TrkA) and low-affinity NGF receptor (LNGFR/p75NTR). 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.

Storage

The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.
