IL-17F Protein, Human
Based on 1 Customer Validation
IL-17F is an inflammatory homodimeric cytokine that induces many proinflammatory cytokines and chemokines. IL-17F also induces antimicrobial peptides. IL-17F plays a protective role in colon cancer development and can be used for the research of autoimmune diseases, infection and cancer. IL-17F Protein, Human is a recombinant human IL-17F protein and is expressed in E. coli. It consists of 133 amino acids (R31-Q163).
- Species: Human

Biological Activity
IL-17F is an inflammatory homodimeric cytokine that induces many proinflammatory cytokines and chemokines. IL-17F also induces antimicrobial peptides. IL-17F plays a protective role in colon cancer development and can be used for the research of autoimmune diseases, infection and cancer[1][2]. IL-17F Protein, Human is a recombinant human IL-17F protein and is expressed in E. coli. It consists of 133 amino acids (R31-Q163).
Interleukin-17F (IL-17F) belongs to the IL-17 cytokine family. IL-17F is expressed in activated CD4 T cells, activated monocytes, basophils and mast cells. IL-17F can be produced by differentiated TH17 cells, lamina propria T cells, memory CD4+ T cells, γδ T cells and NKT cells[1].
The human IL-17F shares 55.90% amino acid sequence identity with mouse and 57.14% identity with rat.
IL-17F is an inflammatory cytokine that induces many proinflammatory cytokines and chemokines, including TGF-β, IL-2, ICAM1, GM-CSF, CCL2, CCL7, TSLP, MMP13, IL-6 and CXCL1. IL-17F also induces antimicrobial peptides including hBD-2, S100A7, S100A8 and S100A9 with IL-22 and can synergize with IL-23 in human eosinophils to promote the production of IL-1β and IL-6. IL-17F is a homodimeric cytokine. IL-17F shares the most similarities with IL-17A (50% homology) and can be produced as an IL-17AF heterodimer. IL-17A, IL-17F and IL-17A/F use the same receptor complex: IL-17RA and IL-17RC heterodimer. They trigger qualitatively similar signaling pathways, and IL-17F exhibits the lowest biological activity. IL-17F shows about 100–1000 times lower affinity to the IL-17RA subunit than IL-17A, and does not compete with IL-17A binding to IL-17RA[1][2].
IL-17F plays a protective role in colon cancer development and can be used for the research of autoimmune diseases, infection and cancer[1][3][4].
IL-17F (50 ng/mL; 16-24 h) induces GRO-α, IL-6, and IL-8 secretion in human primary foreskin fibroblast (BJ) cells[5].
IL-17F binds weakly to IL-17RA.Fc with an EC50 > 2000 ng/mL, whereas IL-17A binds IL-17RA.Fc with a value of 19 ng/mL, the IL-17F/IL-17A heterodimer has an EC50 of 329 ng/mL[5].
IL-17F (0-150 ng/mL; 0-72 h) increases the cell viability of PC-3 and DU145[6].
IL-17F (100 ng/mL; 24 h) stimulates the malignant phenotypes of PCa cells and activates PI3K/AKT signalling pathway in PCa cells[6].
Measured by its ability to induce the expression of IL-6 in NIH/3T3 mouse embryonic fibroblast cells. The ED50 is <40 ng/mL, corresponding to a specific activity of >5.0 × 104 units/mg.

Product Properties
Lyophilized powder
1.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.2 with trehalose.
Please refer to the lot-specific COA for specific buffer information.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in 4 mM HCl. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
