Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. It activates the innate immune system.Biological Activity:Activation of TLR5 in human epithelial cell assays based on NF-kappaB luciferase fusions, on expression of IL-8 (CXCL8), CCL20, inducible nitric oxide synthase, beta-defensin 2 and matrilysin (MMP-7). Maturation of dendritic cells in in vitro and in vivo assays. Adjuvant activity on foreign antigens delivered by subcutaneous and intranasal routes in mice.Endotoxin:≤0.1EU/ug purified protein (LAL)Specificity: Binds to human and mouse TLR5 (Toll-like receptor 5).Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
