Mouse IFNG / Interferon Gamma Protein

50709-MNAH

Activity: (1) Measured by its binding ability in a functional ELISA. (2) Immobilized mouse IFNG at 10 μg/mL (100 μL/well) can bind mouse IFNGR1-Fc (Cat:50705-M02H). The EC50 of mouse IFNGR1-Fc (Cat:50705-M02H) is 0.04-0.08 μg/mL. (3) Measured in antiviral assay using L929 cells infected with vesicular stomatitis virus. The ED50 for this effect is typically 0.5-2 ng/mL.

More info

Protein Construction: A DNA sequence encoding the mouse IFNG (NP_032363.1) (Met1-Cys155) was expressed and purified.

Formulation: Lyophilized from sterile PBS, pH 7.4.1. Normally 5% - 8% trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.2. Please contact us for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.

Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Interferon Gamma Background Information: IFN gamma, also known as IFNG, is a secreted protein which belongs to the type I I interferon family. IFN gamma is produced predominantly by natural killer and natural killer T cells as part of the innate immune response, and by CD4 and CD8 cytotoxic T lymphocyte effector T cells once antigen-specific immunity develops. IFN gamma has antiviral, immunoregulatory, and anti-tumor properties. IFNG, 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. The IFNG monomer consists of a core of six α-helices and an extended unfolded sequence in the C-terminal region. IFN gamma is critical for innate and adaptive immunity against viral and intracellular bacterial infections and for tumor control. Aberrant IFN gamma expression is associated with a number of autoinflammatory and autoimmune diseases. The importance of IFN gamma in the immune system stems in part from its ability to inhibit viral replication directly, and most importantly from its immunostimulatory and immunomodulatory effects. IFNG also promotes NK cell activity.
