2000L規模のバイオリアクタープロセスにおける抗体還元の防止
この例において、2000L規模における分子Aの製造は、プロテインA捕捉クロマトグラフィーステップ後に、キャンペーン2において顕著な抗体還元を示した。その後の製造キャンペーン(キャンペーン3)において、図3に描写するように最初の回収プロセスにおいて活性炭素濾過ステップを実装した(Millistak+CR40、Millipore)。このキャンペーンにおいて、抗体還元は検出されなかった。
400L規模のバイオリアクタープロセスにおける抗体還元の防止
この例において、400L規模における分子Bの製造は、プロテインA捕捉クロマトグラフィーステップ後に、キャンペーン1のバッチ1において顕著な抗体還元を示した。その後の製造バッチにおいて、図3に描写するように最初の回収プロセスにおいて活性炭素濾過ステップ(Millistak+CR40、Millipore)を実装した。これらのバッチにおいて、抗体還元は検出されなかった。
サンプルは、濾過後(炭素濾過有り及び無し)における分子Bの製造キャンペーンから採取されたが、その後、低酸素条件下で、規模を縮小したモデルの製造プロセスを使用して精製された。このモデルは、サンプルに窒素ガスを少なくとも30分間にわたって注入することを含み、これはその後、これらの条件下で一晩貯蔵された。
