Interferon-γ is a potent multifunctional cytokine which is secreted primarily by activated NK cells and T cells. Originally characterized based on anti-viral activities, IFN-γ also exerts anti-proliferative, immunoregulatory, and proinflammatory activities. IFN-γ plays a role in class I antigen presentation pathway by inducing catalytic proteasome subunit replacement with immunoproteasome subunit. IFN-γ can upregulate MHC class I and II antigen expression by antigen-presenting cells.
Product DetailsProduct Details
- Source
- Human IFN-γ, amino acids Gln24-Gln166 (Accession # NM_000619) was expressed in E. coli.
- Molecular Mass
- The 144 amino acid N-terminal methionylated recombinant protein has a predicted molecular mass of 16,907 Da. The DTT-reduced protein and the non-reduced protein migrate at approximately 17 kDa by SDS-PAGE.
- Purity
- > 95%, as determined by Coomassie stained SDS-PAGE
- Formulation
- 0.1 µm filtered protein solution is in 10 mM Sodium succinate, 5% Mannitol, pH 5.
- Endotoxin Level
- Less than 0.1 EU per µg protein as determined by the LAL method
- Concentration
- 500 µg/mL
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- ED50 = 1 - 6 ng/mL as determined by the dose-dependent cytotoxicity of human colon cancer cell line HT-29 cells. Deep Blue Cell Viability™ Kit (Cat. No. 424701) is used to measure the proliferation.
