Recombinant Human Interferon-g(rHu IFN-g)

• Source:

  Escherichia coli.

• Purity:

  > 98 % by SDS-PAGE and HPLC analyses.

• Bioactivity:

  Fully biologically active when compared to standard. The ED50 as measured in anti-viral assays using human HeLa cells infected with encephalomyocarditis (EMC) virus is 0.15-0.80 ng/ml.

• Molecular Weight:

  Approximately 16.9 kDa, a single non-glycosylated polypeptide chain containing 144 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 PBS, pH 7.4.

• Host or Source:

  Human

• CAS Number:

  9000-83-3
