Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM MES (pH6.0) containing 20% glycerol, 0.1M NaCl, 1mM EDTA. Ifng, also known as interferon gamma, is a member of the type II interferon family. This protein is a soluble cytokine with antiviral, immunoregulatory and anti-tumor properties and is a potent activator of macrophages. Mutations in this gene are associated with aplastic anemia. Recombinant canine Ifng protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
