Product Description: Interleukin-17A/F (IL-17A/F) is a heterodimer that is composed of the interleukin-17A (IL-17A) and interleukin-17F (IL-17F) members of the IL-17 family of cytokines. IL-17A/F is produced by T helper 17 cells (Th17) following interleukin-23 (IL-23) stimulation. IL-17A/F signals through the IL-17RA/IL-17RC receptor complex and functions to regulate inflammatory responses. IL-17A/F induces chemokine and airway neutrophilia production, similar in function to IL-17A and IL-17F homodimers. In regard to these functions, IL-17A/F is less active than the IL-17A homodimer and shows greater activity than the IL-17F homodimer. Human and rat IL-17A/F are active on mouse cells.
Source: E. coli
Purity: >95% determined by reducing and non-reducing SDS-PAGE
Formulation: Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 0.1% Trifluoroacetic Acid (TFA)
Endotoxin Level: <1.00 EU/ug as measured by kinetic LAL
Molecular Weight: 15.1 / 30.2 kDa
Stability and Storage: 12 months from date of receipt when stored at -20°C to -80°C as supplied. 1 month when stored at 4°C after reconstituting as directed. 3 months when stored at -20°C to -80°C after reconstituting as directed.
Species: Rat
Activity Assay: Rat IL-17A/F is fully biologically active when compared to standard. The activity is determined by the ability to produce mouse IL-6 by NIH-3T3 cells.
