  • Purification of VWF
    Patent number: 10626164
    Abstract: The present invention provides a method of purifying multimeric von Willebrand Factor (VWF) from a solution comprising multimeric VWF and contaminants. The method comprises passing the solution through a chromatography column comprising beads of a mixed mode chromatography resin coated with a size-exclusion inactive shell and collecting the multimeric VWF which passes through the column without binding to the resin.

  • METHODS OF PURIFYING POLYPEPTIDES
    Publication number: 20190330267
    Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a change that is opposite to the change of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.

    Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a charge that is opposite to the charge of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.
