Description
Interferon-gamma (IFN-γ), also known as Type II interferon or immune interferon, is a pleiotropic cytokine which is now recognised as an important modulator of the immune response. Mature human IFN-γ exists as a non-covalently linked homodimer of 20-25 kDa variably glycosylated subunits.

Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Biological Activity
The ED50 as determined by an anti-viral assay using murine L929 cells infected with encephalomyocarditis (EMC) virus is less than 0.8 ng/ml, corresponding to a specific activity of > 1.3 × 106 IU/mg. Fully biologically active when compared to standard.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4
Reconstitution
Brief centrifugation prior to opening is recommended to bring the contents to the bottom. Reconstitute to a concentration of 0.1-1.0 mg/mL in sterile distilled water or an aqueous buffer containing 0.1% BSA. The stock solution should be divided into aliquots and stored at ≤ -20°C.
