Recombinant flagellin from S. typhimurium - TLR5 agonist
Recombinant flagellin from S. typhimurium
Bacterial flagellin, a TLR5 ligand, is a potent T-cell antigen and has potential as a vaccine adjuvant. Unlike other TLR agonists, flagellin tends to produce mixed Th1 and Th2 responses rather than strongly Th1 responses.
Flagellin Flic VacciGrade™ is suitable for preclinical studies. It is prepared under strict aseptic conditions. It is guaranteed sterile and thoroughly tested for the presence of endotoxins.
Flagellin Flic VacciGrade™ is for research use only, not for use in humans.Back to the top

Flagellin FliC is a recombinant flagellin protein encoded by the fliC gene from Salmonella typhimurium. Bacterial flagellin, a TLR5 ligand, is a potent T-cell antigen and has potential as a vaccine adjuvant.
Unlike other TLR agonists, flagellin tends to produce mixed Th1 and Th2 responses rather than strong Th1 responses .
It has been demonstrated that flagellin can act as a potent adjuvant in flu vaccines [2, 3].
Furthermore, flagellin can also signal through the NLRC4 inflammasome , although it is not known whether this pathway contributes to the adjuvant activity of flagellin.
