Background:
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. In T-helper cells, IL-2 induces the synthesis of IFN-gamma and other cytokines. IFN- gamma acts synergistically with IL-1 and IL-2 and appears to be required for the expression of IL-2 receptors on the cell surface of T-lymphocytes. Blocking of the IL-2 receptor by specific antibodies also inhibits the synthesis of IFN-gamma.
Description:
Recombinant Interferon gamma is a disulfide-linked homodimeric protein consisting of 134 amino acid residues, and migrates as an approximately 16 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interferon-gamma mature chain was expressed in E. coli.
UniProt
P01580
Synonym(s):
IFNG, Interferon gamma, IFG, IFN
Purity:
≥95% by SDS-PAGE and HPLC
Endotoxin Level:
<0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity:
The ED50 was determined by the cytopathic inhibition assay with murine L929 cells challenged with EMC virus to be 0.1 ng/ml
Formulation:
Lyophilized from 0.2 µm filtered PBS, pH 7.0.
Format:
lyophilized protein
Reconstitution:
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability:
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
