1. LPS (Lipopolysaccharide)

LPS is the component of the outermost layer of the cell wall of Gram-negative bacteria. Two kinds of products, one prepared by isolating rough LPS from cells by phenol-water extraction (Westphal method) (product purified by phenol extraction) and the other purified by ultracentrifugation and washed twice (product purified by ultracentrifugation), are available. These can be used for studies on the induction of various inflammatory responses.
Three LPSs of Proteus vulgaris strains are used for serodiagnosis (Weil-Felix reaction) of rickettsial infections (anthema, epidemic typhus, trombiculiasis). It has been revealed that the LPS O-antigens of Rickettsias and Proteus vulgaris have a consensus structure.
