Heat Killed Salmonella typhimurium

HKST is a heat killed preparation of the flagellated Gram negative bacterium, Salmonella typhimurium.

Recognition of HKST is mediated by TLR2 and TLR4 [1-2].
TLR2 and TLR4 recognize cell wall components from HKST, such as peptidoglycan (PGN) and lipopolysaccharide (LPS) resulting in the production of pro-inflammatory cytokines, such as IL-6 and TNF-α [1].

InvivoGen’s HKST is a potent agonist of TLR2 and TLR4.
