The original described IL-17 protein, now known as IL-17A, was identified from a CD4+ T cells DNA library. IL-17 can be induced from primary peripheral blood CD4+ T cells upon stimulation. Supernatant from cells transfected with IL-17 induced IL-16 and IL-18 production and enhanced the surface expression of the intraCellular adhesion molecule-1 (ICAM-1) in human fibroblasts. Source:Recombinant protein corresponding to human IL-17A, a disulfide-linked homodier of two 136aa polypeptide chains, expressed in E. coli. Molecular Weight: ~31kDBiological Activity:The ED50, as determined by the dose-dependent induction of IL-6 in primary human foreskin fibroblasts, is <2ng/ml, corresponding to a specific activity of >5x10e5units/mg.Endotoxin:<0.1ng/ugStorage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
