Descrizione

Recombinant Protein

The functional form of Recombinant Human beta-NGF is a non-covalently-linked homodimer of two 13.5 kDa, polypeptide monomers that each contain 120 amino acids and three disulfide bonds, which are required for biological activity. This product is shipped at ambient temperature. For storage, handling and reconstitution information, please see the lot-specific Certificate of Analysis

Nerve growth factor (NGF) influences the survival and differentiation of a variety of neuronal and nonneuronal cells. The actions of this polypeptide result from binding to specific cell surface receptors which are present as both high and low affinity sites. Although both types of receptor bind NGF only the high affinity form is capable of signal transduction. Cross-linking studies with 125I-NGF have shown that the high affinity receptor of rat PC12 cells forms an Mr 158,000 complex with NGF while the low affinity receptor forms an Mr 100,000 complex. Full length cDNA clones for both the human and rat NGF receptor genes have been produced and sequenced, revealing greater than 90% homology between the two species. NGF exhibits nerve growth stimulating activity and is involved in the regulation of growth and the differentiation of sympathetic and certain sensory neurons. Further, NGF stimulates division and differentiation of sympathetic and embryonic sensory neurons. Mutations in the NGF gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5), and dysregulation of NGF gene expression is associated with allergic rhinitis.
