  • MEASURING DEGREE OF POLYMERISATION FOR MENINGOCOCCAL CAPSULAR SACCHARIDES THAT CONTAIN SIALIC ACID
    Publication number: 20110159029
    Abstract: 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.
