    摘要: Three conjugation methods for use with the capsular saccharide of Streptococcus agalactiae. In the first method, reductive animation of oxidized sialic acid residue side chains is used, but the aldehyde groups are first aminated, and then the amine is coupled to a carrier via a linker. In the second method, sialic acid residues and/or N-acetyl-glucosamine residues are de-N-acetylated to give amine groups, and the amine groups are coupled to a carrier protein via a linker. In the third method, linkage is via galactose residues in the capsular saccharide rather than sialic acid residues, which can conveniently be achieved using galactose oxidase.

    摘要: An ADP-ribosylating toxin from Listeria monocytogenes is disclosed, together with mutant toxins and uses therefor. There is only a low level of sequence identity between this toxin and known toxins such as the iota toxin from Clostridium perfringens.

    摘要: The degree of polymerisation (DP) is an important parameter for analysis of saccharide antigens, particularly in glycoconjugates. The invention provides methods that can be used to measure DP for capsular saccharides, particularly for meningococcal saccharides e.g. from serogroups W135 and Y. A preferred method is based on reduction of terminal sialic acid residues on saccharides, with DP then being calculated by comparing the molar ratio of total sialic acid to reduced sialic acid.

    摘要: Cytotoxic T-cell epitopes from C.pneumoniae proteins have been empirically determined. The epitopes from corresponding C.trachomatis proteins have also been identified, and some of these are identical to those from C.pneumoniae. The empirical method showed that algorithmic prediction was inadequate. The epitopes are useful for immunisation and/or diagnosis.
