General description

Recombinant human Interferon-γ (IFN-γ) is expressed in human 293 cells as a glycoprotein with a calculated molecular mass of 16 kDa. This protein is manufactured in human cells using an all-human production system, with full chemically defined ingredients and with no serum. The human cells expression system allows human-like glycosylation and folding, and often supports better stability of the protein in culture. The bioactivity of IFN-γ expressed in human 293 cells is significantly higher compared to bacterially expressed IFN-γ.
Interferon-γ (IFN-γ) is a pleotropic cytokine, encoded by the gene mapped to human chromosome 12q15. It is a non-covalent homodimer with two identical 17kDa polypeptide chains. It belongs to the type II class of interferons.


It has also been used for cytokine treatment of human islets to evaluate the activation of hypoxia inducible factor 1 α (HIF1α) targets, in vitro.
Interferon-γ human has been used in cytometric bead array to measure the levels of interferon-γ in the sample.

Biochem/physiol Actions

IFN-γ is a dimerized soluble cytokine that is the only member of the type II class of interferons.
Interferon-γ (IFN-γ) plays an essential role in function of virtually all immune cells and both innate and adaptive immune responses. IFN-γ exhibits various biological effects, such as antiviral activity, inhibition of cell or tumor growth and promotion of terminal differentiation of B cells into immunoglobulin-producing cells. This cytokine also activates macrophages, increases cytotoxicity of natural killer cells and promotes T cell cytotoxicity. In addition to antiviral activity, recombinant human IFN-γ is a potent modulator of immune responses and modifies cellular processes.



Physical form

Supplied as a lyophilized powder containing phosphate buffered saline.

Analysis Note

The biological activity of recombinant human IFN-γ was tested in culture in a viral resistance assay. The ED50 is defined as the effective concentration of IFN-γ that allows 50% cell growth in an antiviral cell based bioassay.
