生物活性

1.Measured by its binding ability in a functional ELISA. Immobilized Recombinant human IL17RA at 2 μg/mL (100 μL/well) can bind Recombinant human IL-17A, the EC₅₀ of human IL-17A is 32.5-130 ng/mL.
2.Measured by its ability to induce IL-6 secretion by Hela cells. The ED₅₀ for this effect is 2.64-10.58 ng/mL, corresponding to a specific activity of 9.45×10⁴~3.79×10⁵ units/mg.

复溶

Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。

背景信息

IL17, also known as IL17a and CTLA8, is a is a 15-20 kDa glycosylated cytokine which belongs to the IL-17 family. The IL-17 family of cytokines includes six members, IL-17/IL-17A, IL-17B, IL-17C, IL-17D, IL-17E/IL-25, and IL-17F, which are produced by multiple cell types. IL17A promotes protective mucosal and epidermal inflammation in response to microbial infection .It induces chemokine production, neutrophil influx, and the production of antibacterial peptides .IL17A additionally enhances the production of inflammatory mediators by rheumatoid synovial fibroblasts and contributes to TNF alpha induced shock . In contrast, it can protect against the progression of colitis by limiting chronic inflammation . IL17A encourages the formation of autoreactive germinal centers and exacerbates the onset and progression of experimental models of autoimmunity .
