Patents by Inventor Anna Akerblom

Anna Akerblom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20250269352
    Abstract: The present invention relates to porous cross-linked agarose gel beads which have a low agarose content, a method for the preparation of the beads and their use in chromatographic applications. The beads are suitable for the separation/purification of biomolecules from a biological sample. Due to the high porosity of the beads, they are especially suitable for separation/isolation of larger particles, such as virus particles e.g. adeno virus.

  • Publication number: 20200141912
    Abstract: A method of continuous separation of a plasmid from a process feed in an apparatus with at least three chromatography columns packed with separation matrix particles, wherein while one chromatography column is loaded with the process feed, another chromatography column is eluted with an eluent to recover the separated plasmid, and yet another chromatography column is eluted with a further eluent to remove contaminants.

  • Patent number: 10041050
    Abstract: The present invention relates to a method for endotoxin removal from a sample comprising the following steps: combining the sample comprising one or more target molecule(s) with a chromatography media comprising beads having an inner porous core functionalized with ligands capable of binding endotoxin and an outer porous layer without functional groups and a pore size small enough to exclude the target molecule from the inner core; and collecting the sample from the media, wherein the sample comprises an endotoxin level which is at least 75% less, preferably 90% less, than before the removal and the yield of the target molecule is at least 75%.
