Recombinant :
Recombinant Rat Interferon-γ (rRtFN-γ) Source :
Escherichia coli. Molecular Weight :
Approximately 15.6 kDa, a single non-glycosylated polypeptide chain containing 135 amino acids. Purity :
>95% by SDS-PAGE and HPLC analyses. Biological Activity :
Measured in an antiviral assay using L929 mouse fibrosarcoma cells infected with encephalomyocarditis (EMC) virus. The ED50 for this effect is typically 1-3 ng/mL, corresponding to a Specific Activity of ＞3.3 x 105 IU/mg. Physical Appearance :
Sterile Filtered White lyophilized (freeze-dried) powder. Formulation :
Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4. AA Sequence :

Less than 1EU/mg of rRaIFN-γ as determined by LAL method. Reconstitution :
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions. Storage :
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. Usage :
This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China Description :
Interferon-gamma (IFN-γ, also known as Type II interferon or immune interferon) is a cytokine produced primarily by T-lymphocytes and natural killer cells. The protein shares no significant homology with IFN-β or the various IFN-α family proteins. Mature IFN-γ exists as noncovalently-linked homodimers. Human IFN-γ is highly species specific and is biologically active only in human and primate cells. IFN-γ was originally characterized based on its antiviral activities. The protein also exerts antiproliferative, immunoregulatory and proinflammatory activities and is thus important in host defense mechanisms. IFN-γ induces the production of cytokines, upregulates the expression of class I and II MHC antigens, Fc receptor and leukocyte adhesion molecules. It modulates macrophage effector functions, influences isotype switching and potentiates the secretion of immunoglobulins by B cells. IFN-γ also augments TH1 cell expansion and may be required for TH1 cell differentiation.
