• Sequence Length: 155

• Domain: 4 helix cytokine core
• Host Note: Optimized DNA sequence encoding Mouse Interferon gamma mature chain was expressed in Escherichia Coli.
• Endotoxin: Endotoxin content was assayed using a LAL gel clot method.; Endotoxin level was found to be less than 0.1 ng/ug (1EU/ug).
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
• Molecular Weight Note: Native Mouse IFN-g, generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 16 kDa. ; Recombinant Interferon gamma is a disulfide-linked homodimeric protein consisting of 134 amino acid residue subunits, and migrates as an approximately 16 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
• Preparation and Storage: The lyophilized protein is stable for at least 2 years from date of receipt at -20 degree C.; Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C for six months, with a carrier protein without detectable loss of activity. ; ; Avoid repeated freeze/thaw cycles.

Related Product Information for IFN-gamma recombinant protein

IFN-gamma is produced mainly by T-cells and natural killer cells activated by antigens, mitogens, or alloantigens. It is produced by lymphocytes expressing the surface antigens CD4 and CD8. IFN gamma receptors are expressed on all types of human cells with the exception of mature erythrocytes.IFN-gamma- receptor complexes are rapidly internalized by endocytosis. IFN-gamma has antiviral and antiparasitic activities and also inhibits the proliferation of a number of normal and transformed cells. Interferon-gamma synergises with TNF-alpha and TNF-beta in inhibiting the proliferation of various cell types. The growth inhibitory activities of IFN-gamma are more pronounced than those of the other interferons. However, the main biological activity of IFN-gamma appears to be immunomodulatory in contrast to the other interferons that are mainly antiviral. n T-helper cells IL2 induces the synthesis of IFN-gamma and other cytokines. IFN- gamma acts synergistically with IL1 and IL2 and appears to be required for the expression of IL2 receptors on the cell surface of T- lymphocytes. Blocking of the IL2 receptor by specific antibodies also inhibits the synthesis of IFN-gamma.
