Abstract
Description
ヒトプロテインCの調製
組換えヒトプロテインC(r−hPC)を、Yan、米国特許4,981,952に記載されており、その教示全体が参照として本明細書に組み込まれている方法のような、当業者に周知の方法によって、ヒト腎臓293細胞にて調製した。ヒトプロテインCをコードする遺伝子は、Bangら、米国特許4,775,624に記載請求されており、その教示全体は参照として本明細書に組み込まれている。293細胞におけるヒトプロテインCの発現に用いられるプラスミドには、Bangら、米国特許4,992,373に記載され、その教示全体が参照として本明細書に組み込まれている、プラスミドpLPCを用いた。プラスミドpLPCの構造はまた、ヨーロッパ特許公報0 445 939、およびGrinnellら、1987、Bio/Technology 5:1189-1192に記載されており、その教示全体はまた参照として本明細書に組み込まれている。手短に説明すると、そのプラスミドを293細胞に移入し、それから安定な形質転換体を同定し、無血清培養液にて継代培養して育てた。発酵の後、精密濾過法により無細胞培養液を得た。
組換えヒトプロテインCの活性化
ウシ トロンビンを、50mM HEPES溶液存在下、pH7.5、4℃の条件で活性化CH−セファロース 4B(Pharmacia)に結合させた。この結合反応は、カラムに詰め込んでおいた樹脂上で起こり、今回は約5000単位トロンビン/mL樹脂を用いた。トロンビン溶液をカラムを通して約3時間循環させ、2−アミノ−エタノール(MEA)を循環溶液中0.6mL/Lの濃度になるまで加えた。MEAを含んだ溶液をさらに10から12時間循環させ、樹脂上の未反応アミンを完全にブロックした。ブロックした後、トロンビン結合樹脂をpH6.5の1M NaCl、20mMトリス溶液10カラム体積で洗浄して非特異的に結合した全てのタンパク質を除去し、活性化緩衝液で平衡化した後に、活性化反応に用いた。
