General description
NGF-β gene is mapped to human chromosome 1p13.2.
Recombinant human β-NGF is expressed in human 293 cells as a homodimer (non-disulfide bonded) of 120 amino acids, with a calculated molecular weight of 13.5 kDa (monomer). Nerve growth factor β (β-NGF) is a neurotrophic factor structurally related to BDNF, NT-3 and NT-4. The production of natural β-NGF occurs in epithelial cells, and the pituitary gland.
Biochem/physiol Actions
A mutation in the NGF-β gene is implicated in the loss of pain perception.
Nerve growth factor β (β-NGF) is a potent neurotrophic factor that signals through its receptor β-NGFR, and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems. β-NGF promotes the survival and cholinergic phenotype of basal forebrain cholinergic neurons and stimulates neurite outgrowth of embryonic trigeminal motor neurons in vitro.
Physical form
This product is lyophilized from PBS.
Preparation Note
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile DDW containing 0.1% endotoxin-free recombinant human serum albumin, to a final concentration of 100 μg/ml.
Store product at –20 °C. The product retains activity for at least 2 years as supplied. After initial thawing it is recommended to store the protein in working aliquots at –20 °C.
Analysis Note
The specific activity is determined by the dose dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).
Disclaimer
The product retains activity for at least 2 years as supplied. After initial thawing it is recommended to store the protein in working aliquots at -20 °C.

The neurodevelopmental hypothesis of schizophrenia has been widely accepted. In light of our previous microarray data, two neurodevelopment-related genes were focused on inclduing the N-acylsphingosine amidohydrolase 1 gene (ASAH1) and the nerve growth factor gene (NGF). The evidence that ASAH1
