Recombinant Human IFNG, His-tagged

Cat.No.: IFNG-24H
Product Overview: Recombinant Human IFNG was produced in the endosperm tissue of barley grain (Hordeum vulgare).
Description: IFN-gamma, a type II interferon and an acid-labile interferon, is mainly produced by CD4 and CD8 T-lymphocytes and natural killer cells activated by antigens, mitogens or alloantigens. IFN-gamma shows no significant homology with IFN-beta or IFN-alpha. IFN-gamma has antiviral and antiparasitic activities and exhibits also immunoregulatory and proinflammatory activities. IFN-gamma induces cytokine production and promotes antigen presentation by up regulating the expression of MHC proteins as well as other antigen proteins. In contrast to other interferons, which are mostly antiviral, the main activity of IFN-gamma seems to be immunomodulatory. Human IFN-gamma is species-specific and is only biologically active in human and primate cells.
Source: Barley grain (Hordeum vulgare)
Species: Human
Tag: His
Form: Sterile filtered through a 0.2 μm filter. Lyophilized from PBS pH 7.2
Bio-activity: Recombinant human IFN-gamma was determined by its dose dependent cytostatic effect, in the presence of TNF-alpha, on HT-29 (human carcinoma) cells. The ED50 for this effect is typically below 0.2 ng/ml corresponding to specific activity of >5 x 10e6 U/mg. Optimal concentration should be determined for specific applications and cell lines.
Molecular Mass: Recombinant human IFN gamma contains 143 amino acids and a 16 a.a. Histidine-based tag for a total length of 159 a.a. and has a predicted molecular mass of 18.8 kDa. As of glycosilation, the recombinant protein migrates with an apparent molecular mass of 20-25 kDa in SDS-PAGE.
Endotoxin: Endotoxin level is less than 0.005ng per μg of product (0.05EU/μg).
Purity: Greater than 95% by SDS-PAGE gel analysis.
Storage: The lyophilized protein, though stable at room temperature for few weeks, is best stored at -20°C. Reconstituted protein should be used immediately or stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
Reconstitution: Always centrifuge the vial before opening. It is recommended to reconstitute the lyophilized protein in sterile water to a concentration of no less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
