  • Method for dry packing chromatography columns
    Patent number: 9958421
    Abstract: The invention provides a packing method for high efficiency chromatography columns starting from dry swellable particles, as well as columns packed by the method and the use of the columns in separation of biomolecules. In the packing method, an amount of dry swellable particles sufficient to give a swollen volume in a liquid of about 105-120% of the column chamber volume is transferred to the column, the column is closed and the liquid is provided to the column.

  • BI-MODAL HYALURONATE
    Publication number: 20120207701
    Abstract: Formulations and methods for protecting cell layers and tissues exposed to trauma are disclosed. Different molecular mass fractions of the same polymer can be used to better control the physical and chemical properties of the formulation. In this manner the benefits of both fractions, and not just the benefits of the average of the fractions, can be seen in the formulation.
