Recombinant Mouse Interleukin 18, His-tagged

• Cat.No.: Il18-740M
• Product Overview: Recombinant Mouse Il18 was expressed as His-tagged fusion protein in E. coli and purifed by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer. MW: 20.4 kDa.

Specification

• Species: Mouse
• Source: E.coli
• Tag: His
• Protein Length: 36-192aa
• Description: Il18, previously known as interferon-gamma (IFN-gamma)-inducing factor, is an activator of NK cells and a co-inducer of Th1 cytokines. IL-18 is produced from Kupffer cells, activated macrophages, keratinocytes, intestinal epithelial cells, osteoblasts, adrenal cortex cells and murine diencephalon. IL-18 was expressed in E. coli and purifed by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer.
• Form: In 20mM Tris-HCl pH 8.0 containing 10% glycerol
• Molecular Mass: 20.4 kDa (178 aa), confirmed by MALDI-TOF.
