Background
Interleukin-17A (IL-17A) is a cystine-linked homodimeric pro-inflammatory cytokine produced by Th17 cells, a distinct CD4+ T cell lineage (1,2). IL-17A stimulates production of the pro-inflammatory cytokines IL-1β, TNFα, and IL-6. IL-17A also induces production of the neutrophil chemoattractants IL-8, CXCL1, and CXCL6 thereby bridging adaptive and innate immunity (1,2). IL-17A is intimately involved in mucosal immunity against bacterial infections (1,3) and has a putative role in some autoimmune disorders (1,4). IL-17A effects appear to be exerted primarily through binding to IL-17RA (5). IL-17A binding induces production of cytokines, chemokines, and other proteins through activation of the Erk1/2 MAP kinase, PI3K/Akt, p38, and NF-κB pathways (3,4,6). Phosphorylation of some Jaks and Stats has been observed.

Endotoxin
Endotoxin levels are less than or equal to 1 EU / 1 μg mIL-17A.
Purity
A greater than or equal to 95% purity was determined by SDS-PAGE.
Source / Purification
Recombinant mouse IL-17A was expressed in E. coli and is supplied in a lyophilized form
Bioactivity
The bioactivity of recombinant mIL-17A was determined by measuring the secretion of IL-6 by NIH/3T3 cells. The ED50 of each lot is less than or equal to 5 ng/ml.
