DESCRIPTION: Recombinant Human β-‐Nerve Growth Factor/β-‐NGF produced in E. coli is a non-‐glycosylated non-‐covalent homodimer of two 118 amino acid polypeptides each with a molecular mass of 13.4 kD. Accession #: P01138 Synonyms : Beta-‐Nerve Growth Factor, Beta‐NGF, NGF, NGFB FORMULATION : Lyophilized from a 0.2 μM filtered solution of 20mM PB, 250mM NaCl, pH 7.0 SHIPPING: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. STORAGE: Lyophilized protein should be stored at < ‐20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4‐7°C for 2‐7 days. Aliquots of reconstituted samples are stable at < ‐20°C for 3 months. RECONSTITUTION: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-‐thaw cycles. QUALITY CONTROL: Bioactivity*: ED50 is less than 1.0 ng/ml. Specific Activity is greater than 1 x 106 IU/mg. *measuredbythedose-‐dependent stimulationoftheproliferationofhumanTF-1 cells.SpecificActivityisg Purity: Greater than 95% as determined by SEC-HPLC and reducing SDS-‐PAGE. Endotoxin: Less than 0.1 ng/µg (1 IEU/µg).
