Analysis Note

The specific activity was determined by the dose-dependent induction of IL-6 secretion from NDHF adult fibroblasts.

Biochem/physiol Actions

IL-17A belongs to the IL-17 family and is produced by Th17 cells, a subset of T helper cells. Interleukin 17 (IL-17), initially known as CTLA-8, is a T cell expressed polypeptide that appears to be involved in the regulation of the hematopoietic system. IL-17 has been shown to induce IL-6, IL-8, and G-CSF production by fibroblasts; all of these cytokines have demonstrated effects on hematopoiesis. IL-17 induces stromal cells to produce proinflammatory and hematopoietic cytokines, upregulates production of growth factors that promote angiogenesis, and enhances expression of adhesion molecules in fibroblasts.

Physical form

Lyophilized from a 0.2 µm filtered solution of 10 mM Tris-HCl pH 7.4+ 250 mM NaCl

Preparation Note

HumanKine Interleukin-17A (IL-17A), expressed in human HEK 293 cells, is a glycosylated homodimer with an apparent molecular mass of 30-35 kDa due to glycosylation. Production in human 293 cells offers authentic glycosylation. Glycosylation contributes to stability in cell growth media and other applications.
