背景介绍 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. 产品介绍 Recombinant Interferon gamma is a disulfide-linked monomer protein consisting of 135 amino acid residues, and migrates as an approximately 16 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding rat Interferon-gamma mature chain was expressed in E. coli.

询价背景介绍 All known subtypes of IFN-alpha show the same antiviral antiparasitic, antiproliferative activities. Human IFN-alpha is also a potent antiviral substance in murine, porcine, and bovine cell systems. IFN-alpha forms are produced by monocytes/macrophages, lymphoblastoid cells, fibroblasts, and a number of different cell types following induction by viruses, nucleic acids, glucocorticoid hormones, and low-molecular weight substances. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino- terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. IFN-alpha and IFN-beta are thought to bind to the same receptor. Signal transduction mechanisms elicited after binding of IFN-alpha to its receptors involves tyrosine phosphorylation of various non-receptor tyrosine kinases belonging to the Janus kinases. 产品介绍 Recombinant Interferon-alpha 2b is a disulfide-linked monomeric protein consisting of 166 amino acid residues. Interefron alpha 2b migrates as an approximately 19 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Interferon-alpha mature chain was expressed in E. coli.
