Recombinant Rat Interferon-gamma (Rat IFN-γ)
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. It shares 90% amino acid (aa) sequence identity with rhesus IFN-γ, 59%64% with bovine, canine, equine, feline, and porcine IFN-γ, and 37%43% with cotton rat, mouse, and rat IFN-γ. Interferons have had increasing clinical usage in the treatment of a variety of disorders, at times being used in combination with chemo‐ or radiotherapy. IFN-γ increases the potential immunogenicity of vascular endothelial cells by up-regulation of intercellular adhesion molecule-1 (ICAM-1) and class I MHC antigen expression and by induction of class II MHC antigens and certain chemokines.

Sterile Filtered White lyophilized (freeze-dried) powder.
> 97% by SDS-PAGE and HPLC analyses.
The ED50 as determined by an anti-viral assay using murine L929 cells infected with encephalomyocarditis (EMC) virus is less than 0.1 ng/mL, corresponding to a specific activity of > 1.0 × 107 IU/mg. Fully biologically active when compared to standard.
< 0.1 EU per 1μg of the protein by the LAL method.
Lyophilized from a 0.2 μm filtered concentrated solution in 1 × PBS, pH 7.4, 1 mM DTT, 5% Trehalose and 0.05% Tween-80.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 10 mM HAc to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
Shipping and Storage
