Publications (3) Datasheet COA

Overview

Product name Active Recombinant Human IFN-gamma Protein
Catalog No. RP01038
Description Recombinant Human Interferon Gamma Protein is produced by E. coli expression system. The target protein is expressed with sequence ( Gln24-Gln166) of human Interferon Gamma (Accession #NP_000610.2).
Bio-Activity 1.Measured by its binding ability in a functional ELISA. Immobilized Human FNGR1/CD119 at 1 μg/mL (100 μL/well) can bind Human IFNG with a linear range of 0.98-1.97 ng/mL.
2.Measured in a cytotoxicity assay using HT-29 cells. The ED50 for this effect is 1.6-7.4 ng/mL, corresponding to a specific activity of 1.35×105~6.25×105 units/mg.
Purity > 95% by SDS-PAGE.
Endotoxin < 0.1 EU/μg of the protein by LAL method.
Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Species Human
Interferon-gamma (IFN-gamma ) is a secreted protein which belongs to the type II interferon family.Recombinant Human IFN-gamma is a 16.8 kDa protein containing 143 amino acid residues. IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. Interferon-gamma is a central regulator of the immune response and signals via the Janus Activated Kinase (JAK)-Signal Transducer and Activator of Transcription (STAT) pathway.
Synonym IFNG; IFG; IFI
Expressed Host E. coli
Tag No tag
Swiss-Prot P01579-1
Gene ID 3458
Storage Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.
Reconstitution Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
