    摘要: The invention provides a method for releasing capsular polysaccharide from S. aureus type 5 or type 8 cells, comprising the step of treating the cells with acid. The invention further provides a process for purifying capsular polysaccharide from S. aureus type 5 or type 8 cells comprising this method. Other processing steps may be included in the process, such as enzymatic treatment, e.g. to remove nucleic acid, protein and/or peptidoglycan contaminants; diafiltration, e.g. to remove low molecular weight contaminants; anion exchange chromatography, e.g. to remove residual protein; and concentration.

    摘要: Precipitated bacterial capsular polysaccharides can be efficiently re-solubilized using alcohols as solvents. The invention provides a process for purifying a bacterial capsular polysaccharide, comprising the steps of (a) precipitation of said polysaccharide, followed by (b) solubilization of the precipitated polysaccharide using ethanol. CTAB can be used for step (a). The material obtained, preferably following hydrolysis and sizing, can be conjugated to a carrier protein and formulated as a vaccine. Also, in vaccines comprising saccharides from the serogroups A and C, the invention provides that the ratio (w/w) of MenA saccharide:MenC saccharide is >1.

    摘要: An oligosaccharide useful for a Meningitidis A vaccine contains a first mannose unit having a spacer in the alpha configuration at C-1, which spacer is capable of conjugating to a protein, and which is connected to a second mannose unit through a 1,6-linkage which connects C-6 of the first unit to C-1 of the second unit, wherein the 1,6-linkage comprises a phosphonate. Related methods of making such compounds, analogous compounds, or intermediates thereof are also disclosed.

    摘要: Carrier-induced epitopic suppression is of particular concern where multiple conjugates with the same carrier protein are administered simultaneously. To avoid the suppression, the invention minimises the amount of unconjugated carrier protein in a vaccine. The invention provides a composition for immunising a patient against a disease caused by Neisseria meningitidis, wherein (1) the composition comprises conjugates for at least two of the four meningococcal serogroups A, C, W135 and Y, where at least two of the conjugates have a common carrier protein; and (2) the composition includes the common carrier in an unconjugated form at less than 10 μg/ml.
