[Study of a lipopolysaccharide-protein complex from Yersinia pseudotuberculosis in aqueous solutions by light scattering].

Lipopolysaccharide-protein complex isolated from Yersinia pseudotuberculosis forms aggregates in aqueous solutions. Dissociation of aggregates was found by light scattering method for 1 M sodium chloride, 1 M guanidine chloride, and urea solutions. Very large particles were detected also in these solutions and acid media. Little light scattering alterations have been observed for 0.27 g/l solution, and pronounced effect of temperature has been detected for more diluted solutions.
