Measured by its ability to induce IL-6 secretion by NIH‑3T3 mouse embryonic fibroblast cells in the presense of 20 ng/mL TNFα. The ED50 for this effect is 1-6 ng/mL.

IL-17A & IL-17F Heterodimer Protein, Human, Recombinant is expressed in E. coli expression system. The predicted molecular weight is 30.7 kDa and the accession number is Q16552&NP_443104.1.

interleukin 17A,IL-17A,IL-17,IL17,CTLA8

A DNA sequence encoding the human IL17A (Q16552) (Ile20-Ala155) was expressed, constructed the plasmid 1; the human IL17F (NP_443104.1) (Arg31-Gln163) was expressed, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified. Predicted N terminal: Met & Met

A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
