Gene Information

human ... NGF(4803)

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.


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.

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.

Storage and Stability

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).
