  • Publication number: 20120156779
    Abstract: The present invention relates to a method for cell expansion. In the method, preferably a cell culture product is used, such as a microcarrier, or other adherent cell culture surface, comprising degradable polysaccharide, preferably starch, modified with small molecular weight cell-binding ligands. This allows recovery (detachment) of adhered cells to be aided by degradation of the culture surface with enzymatic agents, such as amylase. The method for cell expansion comprises the following steps: a) adding cells, culture medium and cell culture surface comprising a degradable polysaccharide with guanidine group containing ligands to a bioreactor; b) expanding said cells by adherent cell culture; and c) aiding the detachment of said cells by exposing them to a polysaccharidase to degrade the culturing surface.

  • Patent number: 7897257
    Abstract: The present invention relates to magnetic beads suitable for, for example, isolation of proteins, cells, and viruses and also for diagnostic applications and cell cultivation. The magnetic beads are composite beads with an inner core of metal particles, which are coated with an inert synthetic polymer and these are then enclosed in a hydrophilic porous polymer, preferably agarose. This provides porous biocompatible beads without metal leakage. The beads may be used for cell cultivation or for chromatography. When the beads are used for chromatography the agarose layer is preferably provided with ligands having affinity for selected biomolecules.
