Description
1.第1のカラム(21)が結合・溶出方式、最後がウイルス濾過(23)の場合。
2.第1のカラム(21)が結合・溶出方式、第2のカラム(22)が捕獲方式(フロースルー)、最後がウイルス濾過(23)の場合。
3.第1のカラム(21)が結合・溶出方式、第2のカラム(22)が結合・溶出方式、最後がウイルス濾過(23)の場合。
第1のカラム21は、予め調製された溶液、或いは、前述の同時係属中の出願「Method and system for preparation of liquid mixtures(液体混合物の調製のための方法及びシステム)」に開示されたのもの等インライン緩衝液調製ユニット又は構造を使用してリアルタイムで調製された緩衝液のいずれかと平衡になっている。次に、サンプルは、直接、或いは、ポンプ33及び制御回路38、39、40を介した導電率又はpHの調節を伴って、カラム21にローディングされる。サンプルが結合し、非結合のサンプルの洗浄が完了した後、タンパク質が溶出される。
第1と第2のカラム21、22は、予め調製された溶液又は(そのように装備されている場合は)システムのインライン緩衝液調製機能を使用してリアルタイムで調製された緩衝液のいずれかと平衡になっている。この平衡溶液が2つのカラムに対して同一の場合は、これを一緒に実施してもよいが、別のカラムをバイパスして平衡化を順次実施してもよい。
第1と第2のカラム21、22は、予め調製された溶液又は(装備されている場合は)システムのインライン緩衝液調製機能を使用してリアルタイムで調製された緩衝液と平衡になっている。平衡溶液が2つのカラムに対して同一の場合、インラインで一緒これを実施してもよいが、別のカラムをバイパスして順番に平衡化を実施してもよい。この時点では、フィルタ23はインラインでない。
図3は、第1のモデルのモノクローナル抗体のDPC(直接生成物捕獲)生成物に使用される、第1の試験用プラットフォーム用のクロマトグラフィーシステムの構成を示し、以下では「Mab1」と称する。
実際のタンパク質での全ての動作実施に先立ち、緩衝液だけで一連の動作を行い、システムに組み込まれた制御ループの動作の検証と、過渡及び定常状態における、導電率、pH及びUV(タンパク質濃度)の制御機能のプロファイリングを行った。各制御回路を使用し、プロセスの流れを設定値で制御した。
次に、(i)目標の導電率に対するローディング中のサンプルのインライン希釈の実証、(ii)溶出中のカラム後pH調節の実証、及び(iii)溶出中のカラム後タンパク質濃度(UV)調節の実証を目標として、Mab1モノクローナル抗体生成物で実験を行った。
図4は、第2のモデルのモノクローナル抗体のDPC(直接生成物捕獲)生成物に使用される、第2の試験用プラットフォーム用のクロマトグラフィーシステム構成を示しており、以下ではこれを「Mab2」と称する。
次に、(i)サンプルローディング中のカラム前インラインpH(下降)調節の実証、及び(ii)溶出中のカラム後タンパク質濃度(UV)調節の実証を目標として、Mab2モノクローナル抗体生成物で実験を行った。
緩衝液動作では、ポンプが自身の直線的動作範囲で動作していれば、多くの動的な条件にシステムが応答可能であることがわかった。
