General description

Interferon-g (IFN-gamma) is a lymphoid factor which possesses potent anti-viral activity. It has also been shown to stimulate macrophages and NK cells. Human IFN-gamma is a 16.7 kDa protein containing 143 amino acid residues.
Product Source: Human, expressed in E.coli

Application

For most in vitro applications, IFN-gamma exerts its biological activity in the concentration range of 0.1 to 10 ng/mL. Responding cells are (partial list): Lymphocytes.

Linkage

Replaces: IF3

Physical form

Sterile filtered, lyophilized from 10 mM sodium phosphate, pH 7.4.

Storage and Stability

The lyophilized IFN-g, though stable at room temperature, is best stored desiccated at -20°C. After a quick spin, reconstitute in 1x PBS, pH 8.0 to a concentration of 0.5-1.0 mg/mL. Note: Further dilutions should be made into RPMI + 10% FCS or 5% HSA and stored at 4°C for 1 week or -20°C for future use. Reconstituted material should be stored in undiluted aliquots at -20°C for up to six months.

Analysis Note

Specific Activity: Human IFN-gamma is fully biologically active when compared to standards.The ED(50) as determined in a viral resistance assay is ≤ 0.05 ng/mL

Peroxynitrite is a reactive nitrogen species (RNS) that plays critical roles in signal transduction, stress response, and numerous human diseases. Advanced molecular tools that permit the selective, sensitive, and noninvasive detection of peroxynitrite are essential for understanding its pathophysiological functions.
