Mouse IL-17A, His Tag (CT8-M5240) is expressed from human 293 cells (HEK293). It contains AA Ala 26 - Ala 158 (Accession # Q62386-1).
Predicted N-terminus: His
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 15.8 kDa. The protein migrates as 17-19 kDa and 21-24 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

活性（Bioactivity）-Cell based assay
Mouse IL-17A, His Tag (Cat. No. CT8-M5240) stimulates secretion of IL-6 by NIH-3T3 cells. The ED50 for this effect is 2.132-5.005 ng/mL.
Interleukin-17A (IL17A) is also known as cytotoxic T-lymphocyte-associated antigen 8 (CTLA8),which is a proinflammatory cytokine produced by activated T cells. IL17A can regulate the activities of NF-kappaB and mitogen-activated protein kinases. Also,IL17A can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO).Furthermore,IL17A has been found both in glycosylated and nonglycosylated forms. High levels of IL-17 are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis.
