Opis

General description

Interferon-gamma (IFN-gamma) is a regulatory protein produced by activated NK cells and CD4+TCRalpha/beta+, CD8+TCRalpha/beta+, and TCRgamma/delta+ T cells. The biological activities of IFN-gamma include the specific binding to a single class of high affinity receptors. In addition, IFN-gamma can upgrade the number of lymphoid cell functions including the antimicrobial and antitumor responses of macrophages, NK cells, and neutrophils. Recombinant Murine IFN-γ is a 134 amino-acid length protein with a predicted molecular weight of 15.6 kDa. C-terminal truncation due to proteolytic cleavage occurs during E. coli fermentation and results in a 15.1 kDa protein confirmed by mass spectroscopy. SDS-PAGE analysis of Recombinant Murine IFN-γ shows a band that migrates at approximately 11-12 kDa, under nonreducing and reducing conditions.

Product Source: Mouse, expressed in E.coli

Application

For most in vitro applications, IFN-gamma exerts its biological activity in the concentration range of 0.1 to 10.0 ng/mL.

Biochem/physiol Actions

The ED50 as determined by a cytopathic effect inhibition assay with mouse NIH 3T3 cells challenged VSV is ≤ 0.1 ng/mL

Physical form

Sterile filtered, lyophilized from 10mM Sodium Phosphate, pH 7.0 + 25mM NaCl.

Preparation Note

The lyophilized protein is stable for a few weeks at room temperature, but is best stored at -20°C. After a quick spin, reconstitute with Sodium Phosphate, pH 8.0 to a concentration of 1 mg/mL. Further dilutions should be made into RPMI + 10% FCS or 5% HAS and stored at 2-8ºC for one week or -20ºC for future use. Reconstituted IFN-gamma should be stored in undiluted aliquots at -20°C for up to six months from date of receipt.
