Technical Data
Nerve Growth Factor, pro, Recombinant, Human (NGF)
Molecular Biology Storage: -20CShipping: Blue Ice
ProNGF is the pro-form of the neurotrophin nerve growth factor. Like the mature protein proNGF is characterized by the cysteine knot motif consisting of three cysteine bridges. The protein predominantly exists as a non-covalently linked homodimer. Recombinant Human Pro-NGF produced in E.coli is a non-glycosylated, polypeptide chain containing 222 amino acids and having a molecular mass of 49,738 Dalton.
Recombinant Pro-NGF is purified by proprietary chromatographic techniques.

Amino Acid Sequence:

Biological Activity:
The activity of the protein can by measured by its stimulating effect on the proliferation of TF1 cells (Chevalier et al. 1994 Blood 83, 1479-85).
EC50 130 30 pM (TF1 cell assay)
