Introduction
NGF-beta has nerve growth stimulating activity and the complex is involved in the regulation of growth and the differentiation of sympathetic and certain sensory neurons. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5), and dysregulation of this gene's expression is associated with allergic rhinitis.
Description
Nerve Growth Factor-beta Human Recombinant produced in E.Coli is a non-covalently disulfide-linked homodimer, non-glycosylated, polypeptide chain containing 2 identical 121 amino acids with a molecular weight of two 13.6 kDa polypeptide monomers.
The NGF-b is purified by proprietary chromatographic techniques.
The NGF-b is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
The beta-NGF protein was lyophilized from a 0.2% Trifluoroacetic Acid (TFA).
Solubility
It is recommended to reconstitute the lyophilized NGF-b in sterile 18MΩ-cm H2O not less than 100 class="topDotted">Stability
Lyophilized Beta-NGF although stable at room temperature for 3 weeks, should be stored desiccated below -18-7 days and for future use below -18% HSA or BSA).
