  • AUTOMATED OLIGOSACCHARIDE SYNTHESIZER
    Publication number: 20110313148
    Abstract: The technical field of this invention is automated oligosaccharide synthesizers. There is a need in this field for more efficient oligosaccharide synthesizers. For example, the present invention is an apparatus for solid phase oligosaccharide synthesis, which includes a reaction vessel for holding a reaction mixture, such that the reaction vessel is equipped with a temperature control system, a donor vessel for holding a saccharide donor; an activation vessel for holding activator, a pump operably connected to a fluidic valve; an additional fluidic valve connected to the activation vessel, to the first fluidic valve via a first fluid line, and to the reaction vessel via a second fluid line, such that the activator or saccharide donor can be delivered via the second fluidic valve into the first fluid line and then through the second fluid line into the reaction vessel.
