Recombinant Rat Interferon-g (rRa IFN-g)
- CAS Number: 9000-83-3
- Source: Escherichia coli.
- Purity: > 97 % by SDS-PAGE and HPLC analyses.
- Bioactivity: Fully biologically active when compared to standard. 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.
- Molecular Weight: Approximately 15.5 kDa, a single non-glycosylated polypeptide chain containing 134 amino acids.
- Storage Conditions: This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.
- Formulation: 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.
