- SourceBiotinylated Human IL-17A&IL-17F, Avitag,His Tag (ILF-H82W1) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Ala 155 (IL-17A) & Arg 31 - Gln 163 (IL-17F) (Accession # Q16552-1 (IL-17A) & Q96PD4-1 (IL-17F)).Predicted N-terminus: Gly 24Request for sequence
- Molecular Characterization
Biotinylated Human IL-17A&IL-17F, Avitag,His Tag, produced by co-expression of IL-17A and IL-17F, has a calculated MW of 34.1 kDa. Subunit IL-17A&IL-17F is fused with an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The reducing (R) protein migrates as 40-43 kDa due to glycosylation.
- BiotinylationBiotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
- Biotin:Protein RatioThe biotin to protein ratio is 0.5-1 as determined by the HABA assay.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Immobilized Anti-Human IL17A MAb at 2 μg/mL (100 μL/well) can bind Biotinylated Human IL-17A&IL-17F, Avitag,His Tag (Cat. No. ILF-H82W1) with a linear range of 0.2-6 ng/mL (QC tested).
- BackgroundInterleukin-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.
