  • Publication number: 20230221334
    Abstract: Described herein is a method for assessing disulfide bond reduction potential of a protein of interest comprising the following steps: Providing a cell culture fluid sample comprising mammalian cells expressing a protein of interest at a concentration within the range of between 0.2 g/l to 10 g/l Filtering said cell culture fluid sample over at least one filter Displacing O2 in the filtered cell culture fluid sample Collecting at least one sample of the O2-displaced filtered cell culture fluid sample Separating the proteins in said at least one O2-displaced, filtered cell culture fluid sample according to their size under non-denaturing conditions Determining the disulfide bond reduction potential of the protein of interest.

  • Patent number: 9364520
    Abstract: This invention relates to Factor VIII muteins that are covalently bound, at a predefined site that is not an N-terminal amine, to one or more biocompatible polymers such as polyethylene glycol. The mutein conjugates retain FVIII procoagulant activity and have improved pharmacokinetic properties.
