QIFNG Recombinant Protein

Source : Escherichia Coli. Recombinant Equine Interferon-gamma produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 143 amino acids and having a molecular mass of 16.7kDa.The IFN-gamma Equine is purified by proprietary chromatographic techniques. IFN-gamma produced by lymphocytes activated by specific antigens or mitogens.IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions, it is a potent activator of macrophages, and has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.

Product Specifications

Product Name Alternative

Interferon gamma||IFN-gamma||IFNG.

Purification

Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.

Components

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4 and 5% trehalose.

Storage Conditions

Lyophilized Interferon-gamma although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-gamma should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles.

Applications Notes

It is recommended to reconstitute the lyophilized Interferon-gamma in sterile 18M-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. The ED50 as determined by an anti-viral assay using human HeLa cells infected with encephalomyocarditis (EMC) virus is less than 10.0 ng/ml, corresponding to a specific activity of > 1.0 ƒâ€” 105 IU/mg.
