About this Protein

Name

Recombinant Rat IFN-γ (Recombinant Rat Interferon-γ; rRtIFN-γ)；重組大鼠干擾素γ

Synonyms

IFNG; IFG; IFI; IFN-gamma; Immune interferon; interferon gamma; interferon, gamma

Purity

>97% by SDS-PAGE and HPLC analyses.

Biological Activity

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 0.1ng/ml, corresponding to a specific activity of >1.0×10⁷IU/mg.

Physical Appearance

Sterile Filtered lyophilized (freeze-dried) liquid-like powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in 1X PBS, pH7.4, 1mM DTT, 5% Trehalose and 0.05% Tween-80.

Endotoxin

Less than 0.1EU/μg of rRtIFN-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 10mM HAc to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background

Interferon-gamma (IFN-γ), also known as Type II interferon or immune interferon, is a cytokine produced primarily by Tlymphocytes 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. It shares high sequence indentity with murine IFN-γ (86%). 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. Additionally, IFN-γ augments TH1 cell expansion and may be required for TH1 cell differentiation.
