Synonyms |
Immune Interferon, type II interferon, T cell interferon, MAF, IFNG, IFG, IFI, IFN-gamma. |
Introduction |
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. |
Description |
Interferon-gamma Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 144 amino acids and having a molecular mass of 17kDa. The IFN-gamma is purified by proprietary chromatographic techniques. |
Source |
Escherichia Coli. |
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation |
The protein was lyophilized from a 0.2µm filtered concentrated solution in PBS pH 4.5. |
Solubility |
It is recommended to reconstitute the lyophilized Interferon-gamma in sterile distilled water or 20mM AcOH not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Stability |
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. |
Purity |
Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
