Abstract: | A method has been developed for the quantitative spectrophotometric determination of the lipopolysaccharides ofE. coli 675. The maximum absorption of the lipopoly-saccharides fromE. coli 675 (259 nm) coincides with the maximum absorption (259 nm) of a number of polysaccharides from other Gram-negative bacteria, which can be used to determine lipopolysaccharides in various media.All-Union Scientific-Research Institute of Pharmacy, Moscow.
