Patent abstract
GPC (gel permeation chromatography) and size exclusion chromatography with detection by multi-angle light scattering photometry (SEC-MALS) can be used to accurately measure molecular size and molar mass, respectively, of saccharide conjugates. The invention provides (a) a process for measuring the molecular size of a conjugated saccharide antigen within a sample, comprising a step of analyzing the sample by GPC, and (b) a process for measuring the molar mass of a conjugated saccharide antigen within a sample, comprising a step of analysing the sample by SEC-MALS.
