ABSTRACT:
Processes for the electrophoretic analysis of monosaccharides and/or polysaccharides are disclosed. The processes generally first include providing a composition having derivatized mono and/or polysaccharide components which are monosaccharide and/or polysaccharide labelled with a fluorescing charged compound. Then introducing the composition into an electrophoretic medium and applying an electric field across the electrophoretic medium causes the derivatized monosaccharide and/or polysaccharide components to differentially migrate within the electrophoretic medium. Then detecting the derivatized monosaccharide and/or polysaccharide components is accomplished by laser exciting the derivatized monosaccharide and/or polysaccharide components and monitoring fluorescent emission of the derivatized monosaccharide and/or polysaccharide components. The processes provide extremely low detection limits of the labelled components.
