This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Details of Functionality
Fully biologically active when compared to standard. The ED50 as determined by an anti-viral assay using human HeLa cells infected with encephalomyocarditis (EMC) virus is less than 10.0 ng/ml, corresponding to a specific activity of > 1.0 x 10^5 IU/mg.

Background

Interferon-gamma (IFN-gamma), also known as Type II interferon or immune interferon, is a cytokine produced primarily by Tlymphocytesand natural killer cells. The protein shares no significant homology with IFN-beta or the various IFN-alpha family proteins. Mature IFN-gamma exists as noncovalently-linked homodimers. IFN-gamma 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-gamma 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-gamma augments TH1 cell expansion and may be required for TH1 cell differentiation. Equine IFN-gamma shares 73 %~82 % amino acid sequence identity with bovine, canine, feline, and porcine IFN-gamma and 42 %~64 % with cotton rat, human,murine, rat, and rhesus macaque IFN-gamma.
