Formulation |
Lyophilized from a 0.2 μm filtered solution of 20mM PB, pH 7.4 |
Shipping |
The product is shipped at ambient temperature. |
Reconstitution |
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
Storage |
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
Biological Activity |
measured by the dose-dependent induction of IL-6 in primary human foreskin fibroblasts. |
Purity |
Greater than 95% as determined by RP-HPLC and reducing SDS-PAGE. |
Endotoxin |
Less than 0.1 ng/µg (1 IEU/µg). |

Background |
Interleukin-17 is a potent pro-inflammatory cytokine produced by activated memory T cells. There are at least six members of the IL-17 family in humans and in mice. As IL-17 shares properties with IL-1 and TNF-alpha, it may induce joint inflammation and bone and cartilage destruction. This cytokine is found in synovial fluids of patients with rheumatoid arthritis, and produced by rheumatoid arthritis synovium. It increases IL-6 production, induces collagen degradation and decreases collagen synthesis by synovium and cartilage and proteoglycan synthesis in cartilage. IL-17 is also able to increase bone destruction and reduce its formation. Blocking of interleukin-17 with specific inhibitors provides a protective inhibition of cartilage and bone degradation. |
