  • Die Produktion von rekombinanten monoklonalen Antikörpern in Säugetierzellen ist in der biopharmazeutischen Industrie weit verbreitet. Aufgrund ihrer Fähigkeit human-kompatible Proteine mit menschenähnlichen posttranslationale Modifikationen
  • wie zum Beispiel die Glykosylierung
  • werden häufig CHO-Zellen (chinese hamster ovary) als Expressionssystem verwendet. Darüber hinaus wurden Zusammenhänge zwischen Prozessparametern und Zellsuspension überprüft. Aus diesem Grund wurde eine Methode zur Messung der Sedimentationsgeschwindigkeit mittels LUMiSizer
  • einer analytischen Zentrifuge.Zusammenfassend kann die Verwendung des LUMiSizers als at-line Methode zur schnellen Bestimmung von Zelllyse und Zellaggregation eine Alternative zu konventionellen Methoden sein. Production of recombinant monoclonal antibodies in mammalian cells is widespread in biopharmaceutical industry. Therefore
  • Chinese hamster ovary (CHO) cells are mostly used as expression system due to their ability to express human-compatible proteins with human-like post-translational modifications such as glycosylation. Furthermore
  • correlations of process parameters and cell broth characteristics were investigated. For this reason
  • a method for the measurement of the sedimentation velocity was established by using a multi-sample analytical centrifuge
  • called LUMiSizer. In conclusion
  • using the LUMiSizer as an at-line method for fast determination of cell lysis and aggregation can be an alternative to conventional methods.
