IFN-gamma Protein, Mouse (HEK293, His) is the recombinant mouse-derived IFN-gamma protein, expressed by HEK293 , with C-6*His labeled tag. The total length of IFN-gamma Protein, Mouse (HEK293, His) is 133 a.a., with molecular weight of 15-28 kDa.

Background

IFN-gamma is produced by immune cells such as T cells and NK cells, and plays a key role in antibacterial, antiviral, and antitumor responses by activating effector immune cells and enhancing antigen presentation[1][2][5][6].FN-gamma is involved in the regulation of hematopoietic stem cells under developmental and steady-state conditions by affecting their development, quiescence, and differentiation[3][4].IFN-gamma increases the susceptibility of cancer cells to external and internal apoptosis pathways by regulating the expression of Fas/FasL, TNF-related apoptosis-inducing ligand (TRAIL), caspase-8, -3, -7, and -1, survivin, and Bim[5].IFN-gamma mainly interacts with its receptor IFNGR1 through the JAK-STAT pathway to affect gene regulation. After binding to the receptor, the intracellular domain of IFNGR1 opens, allowing downstream signaling elements JAK2, JAK1, and STAT1 to bind, resulting in STAT1 activation, nuclear translocation, and IFN-gamma-regulated gene transcription[6].IFN-gamma achieves antiviral effects by inducing RNA-activated protein kinase R (PKR) and adenosine deaminase RNA-specific-1 (ADAR-1) to activate antiviral proteins[6].IFN-gamma can inhibit the production of IL-4 by TH1 cells and maintain the sustained expression of T-bet[7].As a central effector of cell-mediated immunity, IFN-gamma can enhance antigen recognition through interactions with homologous T cells, amplify antigen presentation through antigen-presenting cells (APCs), increase the production of reactive oxygen species (ROS) and reactive nitrogen intermediates (RNIs), and induce antiviral responses[8].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
