To determine the content of lipopolysaccharide (LPS) in P. aeruginosa aqueous extracts the ELISA was used. Membrane filtration and ultracentrifugation followed by precipitation with ammonium sulfate at 80% saturation and gel filtration on Sephadex G-100 have proved to be the most effective methods for purification of the aqueous extract from LPS.
