Description
図1は、本発明の方法の実施に使用する装置の概略的なフローシートを示す。
本発明を、特に前記物質がタンパク質である場合についてさらに記述する。超臨界的流体の使用、炭水化物、アミノ酸および界面活性剤ポリマー等の種々の安定剤の使用を通じて、安定な乾燥タンパク質/安定剤微粒子の製造が可能であることが判明している。
超臨界的流体は、前記超臨界的流体の流速設定に用いるためのポンプ8により沈降容器に供給した。ライン35中における前記超臨界的流体の温度は、ノズル開口部を通じた膨張に依存して温度が低下することを考慮し、ヒーター17により、粒子形成容器内の温度よりも高い値に設定した。次に、前記調節剤を、あらかじめ決定した流速で、ポンプ9により前記超臨界的流体に添加した。タンパク質および安定剤の溶液は、定常状態(steady state conditions)が保たれている間、ポンプ10により前記粒子形成容器内に注入した。
本実施例では、本発明の方法を、アルカリホスファターゼ(ALP)およびトレハロースの共沈降混合物に用いた。
各カテゴリーにおけるいくつかのバイアルを、以下の各条件(25℃− 60% RH; 30℃− 65% RH; 40℃− 75%)で6ヶ月静置した。t = 0, 1, 2, 3, 6ヶ月時に、前記バイアル内容物のALP活性についてアッセイを行なった。表1に、この安定性調査結果をまとめる。
本実施例では、本発明の方法を、リソチームおよびトレハロースの共沈降混合物に用いた。
