Background: Human β-Nerve Growth Factor (β-NGF) was initially isolated in the mouse submandibular gland. It is composed of three non-covalently linked subunits α; β; and γ; it exhibits all the biological activities ascribed to NGF. It is structurally related to BDNF; NT-3 and NT-4 and belongs to the cysteine-knot family of growth factors that assume stable dimeric structures. Β-NGF is a neurotrophic factor that signals through its receptor β-NGF; and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems. Β-NGF also acts as a growth and differentiation factor for B lymphocytes and enhances B-cell survival. These results suggest that β-NGF is a pleiotropic cytokine; which in addition to its neurotropic activities may have an important role in the regulation of the immune system. Human β-NGF shares 90% sequence similarity with mouse protein and shows cross-species reactivity.

Concentration:

Activity: Measure by its ability to induce TF-1 cells proliferation. The ED₅₀ for this effect is <0.7 ng/mL. The specific activity of recombinant human beta-NGF is > 1 x 10⁶ IU/mg.

Sequence: Ser122-Ala241

Purity: > 98 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from sterile 20 mM sodium citrate, 0.2 M NaCl, pH 3.5.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.

Calculated MW: 14.4 kDa

ObservedMW: 11 kDa
