  • Evaluating mixtures of low molecular weight heparins by chain profiles or chain mapping
    Patent number: 7816144
    Abstract: Methods for analyzing mixtures of polysaccharides, for example heparin such as unfractionated heparin and enoxaparin are described. In some instances, the mixtures are analyzed using fast performance liquid chromatography (FPLC) and high liquid performance chromatography (HPLC), e.g., strong anion exchange HPLC.
    Type: Grant
    Filed: November 16, 2009
    Date of Patent: October 19, 2010
    Assignee: Momenta Pharmaceuticals, Inc.
    Inventors: Zachary Shriver, Daniela Beccati, Ishan Capila, Nur Sibel Gunay, Jennifer Ozug, Steve Wudyka
