a)第一アニオン交換カラムには、出発材料、すなわち、好ましい実施態様において、細胞培養材料がロードされる。これは不純度が高い出発材料である。第二アニオン交換カラムでは、それは溶出(および補填)工程の後に得られる材料であるため、既にある程度精製されている材料がロードされる。
b)第一アニオン交換工程は、二価カチオンの不在下で第一アニオン交換カラムをロードした後に、生成物を溶出するのに、二価カチオンで実施される。
c)第二アニオン交換についてのロードの二価アニオンのpHおよび濃度は、好ましい実施態様にて、ロード(d)のpHが、ロード(a)の後の洗浄(酸性洗浄、例えば洗浄2)のpH、または洗浄工程が用いられないとした場合のロード(a)そのもののpHよりも高いように選択される。さらには、ロード(a)の導電性は酸性洗浄のそれと対比可能であるが、この洗浄が実施されるとした場合には、低いことが好ましい。二価カチオン濃度、すなわちCa++濃度は、工程(b)の溶出バッファーでのpHよりもロード(d)において高い。
d)従って、第一アニオン交換カラムでは、生成物は該カラムと結合するが、第二アニオン交換カラムでは、生成物は結合しない。
本発明者らは、CHO DXB11非経口(parenteral)細胞系に基づいて、組換えヒト第IX因子を発現する組換えCHO細胞系を開発した。組換えヒトフューリンを共発現し、プロFIXのFIXへの細胞内変異を改善するように、細胞系を遺伝子操作した。生成プロセスでは、ケモスタットモードにて懸濁中に細胞を培養させ、それらを、哺乳類または血漿由来のタンパク質が添加されていない合成培地に順応させた。大豆ペプトンを該培地に加え、クローンの産生を改善した。
