Croyez GMP ® IFN gamma (Interferon gamma), Human
Interferon gamma (IFN gamma) is an effective multifunctional cytokine which is released mainly by activated NK cells and T cells. IFN gamma is primarily characterized based on its anti-viral activities, and then been proved to have several functions such as anti-proliferative, immune-regulatory, and pro-inflammatory activities. IFN gamma can upregulate expression of MHC class I and II antigen by antigen-presenting cells.

FEKLTNYSVTDLNVQRKAIHELIQVMAELSPAAKTGKRKRSQMLFQGRRASQ with polyhistidine tag at the C-terminus
UnitProt ID:
P01579
Species of Origin:
Human
Expression System:
Escherichia coli
Endotoxin level:
<0.05 EU per 1 μg of the protein by the LAL method.
Activity:
Measure by its ability to induce cytotoxicity in HT29 cells. The ED50 for this effect is <1 ng/mL. The specific activity of recombinant human IFN gamma is approximately >2 x 106 IU/mg, which is calibrated against the human IFN Gamma WHO Reference Material (NIBSC code: 87/586).
Purity:
>98% as determined by SDS-PAGE analysis.
Form:
Lyophilized
Storage Buffer:
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 0.5 mg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability & Storage:
This product is stable after storage at:
• -20°C for 12 months in lyophilized state from date of receipt.
• -20°C or -80°C for 1 month under sterile conditions after reconstitution.
Avoid repeated freeze/thaw cycles.
Shipping conditions:
Blue ice
