Monoclonal antibody against S. typhimurium flagellin
S. typhimurium Flagellin Detection with Anti-Flagellin FliC
Anti-Flagellin FliC (clone X5A12) is a monoclonal mouse IgG1 antibody against flagellin from Salmonella typhimurium. This antibody was generated by DNA immunization of Balb/c mice with the fliC gene. It has been produced in hybridomas and purified by affinity chromatography.
Anti-Flagellin FliC was screened for its ability to bind purified flagellin from S. typhimurium (FLA-ST) using ELISA. Flagellin is the major component of the bacterial flagellar filament, which confers motility on a wide range of bacterial species. Flagellin is recognized by TLR5 [1] and induces the activation of NF-κB and the production of cytokines and nitric oxide depending on the nature of the TLR5 signaling complex [2].
Key features:
- Reacts with purified and recombinant flagellin from S. typhimurium
- Provided azide-free
- Each lot is functionally tested

Details
Flagellin is the major component of the bacterial flagellar filament, which confers motility to a wide range of bacterial species. This proinflammatory molecule is present in both Gram-negative and Gram-positive bacteria. It is recognized by distinct types of pattern recognition receptors (PRRs).
Extracellular flagellin is recognized by surface-localized Toll-like receptor 5 (TLR5), which promotes the activation of NF-κB and the subsequent production of cytokines [1, 2]. Flagellin is also recognized by the cytosolic NOD-like receptors (NLRs) NAIP5/NAIP6 sensors of the NLRC4 inflammasome [3, 4]. Flagellin monomers are translocated into the host cell cytosol by a mechanism that requires bacterial secretion systems. This triggers the formation of an NAIP-NLRC4 inflammasome leading to caspase-1-mediated secretion of IL-1β and IL-18 [3, 4].
