Human IL-17A&IL-17F Heterodimer Protein, Twin Strep&His Tag (MALS verified)

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.

Human IL-17A&IL-17F Heterodimer Protein, Twin Strep&His Tag, produced by co-expression of IL-17A and IL-17F, has a calculated MW of 18.5 kDa (IL-17A) and 16.8 kDa (IL-17F) . Subunit IL-17A is fused with a Twin Strep tag at the N-terminus and subunit IL-17F is fused with a polyhistidine tag at the N-terminus. The protein migrates as 19-27 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

-20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human IL-17A&IL-17F Heterodimer Protein, Twin Strep&His Tag (Cat. No. ILF-H52W6) at 2 μg/mL (100 μL/well) can bind Human IL-17 RA, Fc Tag (MALS verified) with a linear range of 0.6-10 ng/mL (QC tested).
