Interferon Gamma Protein, Human, Recombinant: Product Information

> 92 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
Measured in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus (VSV) . The EC50 for this effect is typically 0.1-0.5 ng/mL.
Protein Construction
A DNA sequence encoding the human γ-IFN (NP_000610.2) (Met 1-Gln 166) was expressed and purified.
Expressed Host
CHO Stable Cells
Predicted N Terminal
Gln 24
Molecule Mass
The secreted recombinant human γ-IFN consists of 143 amino acids and has a predicted molecular mass of 16.7 kDa. γ-IFN migrates as two bands with apparent molecular mass of 21&25 kDa probably due to different glycosylation.
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Interferon Gamma Background Information

IFN gamma, also known as IFNG, is a secreted protein that belongs to the type II interferon family. IFN gamma is produced predominantly by natural killer and natural killer T cells as part of the innate immune response, and by CD4 and CD8 cytotoxic T lymphocyte effector T cells once antigen-specific immunity develops. IFN gamma has antiviral, immunoregulatory, and anti-tumor properties. IFNG, in addition to having antiviral activity, has important immunoregulatory functions, it is a potent activator of macrophages and has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons. The IFNG monomer consists of a core of six α-helices and an extended unfolded sequence in the C-terminal region. IFN gamma is critical for innate and adaptive immunity against viral and intracellular bacterial infections and tumor control. Aberrant IFN gamma expression is associated with some autoinflammatory and autoimmune diseases. The importance of IFN gamma in the immune system stems in part from its ability to inhibit viral replication directly, and most importantly from its immunostimulatory and immunomodulatory effects. IFNG also promotes NK cell activity.
