Purity ~95% (SDS-PAGE). IL17F, also known as Interleukin-17F, is a cytokine that shares sequence similarity with IL17. It is expressed in activated CD4+ T-cells and activated monocytes. The biological activities mediated by IL17F are similar to those of IL-17. This protein stimulates production of IL-6, IL-8, G-CSF, and regulates cartilage matrix turnover by increasing matrix release and inhibiting new matrix synthesis. It also inhibits angiogenesis and induces production of IL-2, TGF-beta, and monocyte chemoattractant protein-1 in endothelial cells Source: Recombinant protein corresponding to aa24-188 from human IL17F, fused to His-Tag at C-terminal, expressed in insect cell. Molecular Weight: ~16.0kD (142aa), 18-28kD (SDS-PAGE under reducing conditions.) Endotoxin: <1EU/1ug (determined by LAL method) AA
