IL-17F is part of the IL-17 cytokine family which consists of at least seven structurally related proteins (IL-17A, B, C, D, E, F, and A/F). IL-17F homodimer adopts a cysteine knot motif formed through the interactions of four cysteines, one of which is responsible for inter-chain bonding. IL-17F is most closely related to IL-17A, sharing 50% amino acid sequence homology. It is expressed by Th17 cells, along with IL-17A homodimer and IL-17A/F heterodimer. IL-17F has been shown to inhibit endothelial cell angiogenesis and induce increased production of IL-2, TGF-β, and MCP-1, playing a critical role in the regulation of inflammatory reactions and in a variety of auto-immune diseases.

The IL-17A/F heterodimer consists of the monomeric units of IL-17A and IL-17F. It is a naturally expressed and biologically active molecule. While much has been studied about IL-17A and IL-17F, it is still unclear how each distinctively induces the inflammatory response, and what role IL-17A/F also plays in it. It is known that all three cytokines are produced in different amounts, and each has different degrees of pro-inflammatory effects. All seem to interact with the IL-17RA/IL-17RC receptor complex, and signal via the NF-κB pathway to induce secretion of inflammatory cytokines and recruit granulocytes.

BioLegend's purified Poly5166 antibody is IL-17F specific and can be paired with biotinylated Poly5166 to recognize IL-17F or with biotinylated anti-human IL-17A clone BL23 to recognize the IL-17A/F heterodimer.

ELISA Capture - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA Capture applications, a concentration range of 0.2 - 2 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of IL-17A/F recombinant protein ranging from 10.94 to 700 pg/mL is recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The pure Poly5166 (Cat. No. 516601) antibody is useful as the capture antibody in a sandwich ELISA assay.  Poly5166 can be used as a poly-poly pair with biotinylated Poly5166 to recognize human IL-17F, or it can be used as a poly-mono pair with biotinylated BL23 (Cat. No. 512705) to recognize the human IL-17A/F heterodimer (Cat. No. 580609).
