本実施例は、本発明のマクロポーラスポリマーの調製を例示している。有機モノマー相は、次の成分を配合することにより1リッタービーカー中で調製された:180gのジビニルベンゼン混合物(80%DVB/20%EVB)、73gオルトキシレン、147gMIBC及び10.6gBPO(75%純度、25%水分)。これらの量は、122%混合ポローゲン(全モノマー基準)、2.0の親水性ポローゲン/疎水性ポローゲン比率及び4.5%のフリーラジカル開始剤、BPO(全モノマー基準)に相当する。この混合物は、窒素雰囲気下で20分撹拌された。
この実施例は、インシュリン結合容量についての本発明のマクロポーラスポリマーの評価を記載している。約5ml容積の試料は、小規模の試験カラム(内径1.0cm×長さ6.3cm)に充填され、水溶液からウシインシュリンの前端吸着(front adsorption)を評価した;この試験は、ポリマーマトリックスが、典型的な使用条件下で標的プローブ分子(例えば、インシュリン)についての迅速な、効率的な物質移動及び高容量を可能にするか否かを測定するために設計された。加えて、約20mlの試料は、大規模試験カラム(内径1.0cm×長さ25cm)に充填され、インシュリンの分別/分離が遂行された;この試験は、ポリマーマトリックスが典型的なプロセス条件下で満足な性能を提供したことを確認するために行われた。
本実施例は、本発明のマクロポーラスポリマーについてそれらの透過率特性、即ち、圧縮抵抗性の評価法を記載している。ポリマーは、それらの「流れ抵抗」又は1/K値(式3を参照)によって特徴付けられる。
本実施例は、酵素処理をした場合及び酵素処理をしない場合における、本発明のマクロポーラスポリマーを調製することの効果を記載している。酵素処理は、ポリマーの表面汚染(例えば、イオン性又は荷電物質)から生じるビーズ間の望ましくない引力のために使用過程で時折おきる、ポリマーの凝集又は集塊を最小限にする。酵素処理を使用する利点は、結果として生じる球状ポリマー粒子が凝集せず、即ち、粒子がお互いに接着して集塊を形成しないことである。酵素処理はポリマービーズ表面から(重合過程で使用される)分散剤及び沈殿防止剤の痕跡を浄化及び除去し、その結果、カラム内で自由に流れ、均一に詰まるポリマービーズを提供し、延いては使用過程での最小の床容積及び低い圧力降下特性に通じるものであると信じられる。
