| Interferon gamma, Recombinant, Murine (IFNg) is a major interferon produced by mitogenically or antigenically stimulated lymphocytes. It is structurally different from type I interferon and its major activity is immunoregulation. It has been implicated in the expression of class II histocompatibility antigens in cells that do not normally produce them, leading to autoimmune disease. Interferon 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. The synthesis of IFN-gamma is induced, among other things, by Interleukin-2, FGF-basic, and EGF. | | | Catalog # | I1000-01 | | Recombinant protein corresponding to , murine IFNg expressed in E. coli | | Biological Activity | Recombinant Murine Interferon gamma is fully biologically active when compared to standard.
