More Information
Product Details
Synonyms FliC
Product Type Protein
Properties
Source/Host E. coli
Sequence

The native flagellin [FliC] from Salmonella enterica Serovar Typhimurium strain ATCC14028 (aa 1-495) is fused at the N-terminus to a His-tag.

Crossreactivity Human
Mouse
Specificity

Detected by human and mouse TLR5 (Toll-like receptor 5) and mouse NLRC4 (Nod-like receptor [NLR] family caspase activation and recruitment domain [CARD] domain-containing protein 4).

Biological Activity

Activation of TLR5 in human epithelial cell assays based on NF-κB luciferase fusions, in vivo on expression of CCL20 or IL-6. TLR5 can be stimulated in vitro by Flagellin (rec.) at concentration range of 5-50ng/ml and in vivo at a starting concentration of 0.1-1µg/mouse. Inflammasome NLRC4 can be activated at a concentration range of 1-5µg/ml on bone-marrow macrophages in the presence of streptolysin O (SLO, 25µg/ml), a protein that allows delivery of exogenous molecules into the cytosol of living cells.

Description

Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. It activates the innate immune system through the receptor Toll-like Receptor 5 (TLR5) and the intracellular protein NLRC4 (NLR family CARD domain-containing protein 4).
