Description

The recombinant rat IFN-γ is an ~20 kDa factor produced by activated T, B and NK cells and an anti-viral and anti-parasitic cytokine. IFN-γ, in synergy with other cytokines such as TNF-α, inhibits proliferation of normal and transformed cells. Immunomodulatory effects of IFN-γ are exerted on a wide range of cell types expressing the high affinity receptors for IFN-γ. Glycosylation of IFN-γ is not important for its biological activity.

Applications Reported

For research use only, not for diagnostic or therapeutic use. Recombinant rat IFN-γ is biologically active and can protect L929 cell line against viral infection in culture. It is also used as standard cytokine in rat IFN-γ ELISA.

Applications Tested

This recombinant rat IFN-γ has been tested by bioassay using mouse fibroblast cell line L929. The ED₅₀ measured in a L929 protection is <100 pg/ml, corresponding to a specific activity of >1x10⁷ Units/mg.
