Opis

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.

Physical form

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

Preparation Note

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
