title: [Study of molecular heterogeneity and chemical nature of polymeric components of the Meningococcus cell wall].
abstract: The high-molecular fraction of substances of the cell wall of meningococci, groups A and B, isolated in free volume in gel filtration through sepharose 4B and containing both group and intergroup antigens proved to be consisting of 2 subfractions in gel-filtration through Bio-Gel A-150m. Molecular weight of the first was within the range of 100--150 million dalton, and of the second--of 3 to 100 million dalton. In dissociation in sodium deoxycholate the high molecular fraction complex compound of the cell wall of meningococcus strain, group A, isolated from the cerebrospinal fluid of a patient suffering from meningitis broke down into 5 fragments differing in chemical nature and mol wt. There were revealed protein and protein-lipopolysaccharide components with a relatively high mol wt. polypeptide components and low molecular residues of the initial lipopolysaccharide.
