  • Methods of optimizing chromatographic separation of polypeptides
    Patent number: 9766217
    Abstract: Described are methods for determination of peptide specific parameter(s) of a mixture comprising a target peptide and a related impurity (or impurities) to be used in a simulation model of chromatographic separation using mathematical model(s). Also described are chromatographic simulation methods using above determined parameters, as well as computer systems and computer programs for performing one or more of the above method(s).
