DPジペプチド配列の切断
HER2結合Affibody(登録商標)分子Z05494(図1の配列番号8)を、Z02891(図1の配列番号7)から出発して、Z02891のポジション37におけるアスパラギン酸をグルタミン酸に置き換えることによって構築した。次いで、Z05494を、例示の目的で本明細書において記載されている実験において使用した。突然変異した遺伝子を、T7プロモーターを含有し、ヘキサヒスチジン(His6)テールに続いて酸切断を可能にするDPジペプチド配列をコードする発現ベクター中に挿入した。配列番号9のアミノ酸配列(図1)を有し、His6−Z05494で表した発現されたタンパク質を、可溶性生成物として回収し、開始メチオニンを除去した。
本発明によるIgG Fc結合組成物の調製における設計検討
ポリ(エチレングリコール)(PEG)リンカーに、それらのそれぞれのCCTERM-1残基を介して「テール−テール(tail−to−tail)」で連結されている、n=1である2つのIgG Fc結合ポリペプチド、すなわち、2つの単一のドメインを有する2つのモノクローナル抗体(mAb)に結合するための、本発明によるIgG Fc結合組成物におけるポリマーリンカーの最適な長さを評価するために、パイロット実験を実施する。最適なリンカーは、立体障害なく2つのmAbを結合することを可能にするために十分に長いが、両方のIgG Fc結合ドメインが同じmAbに結合するのを可能にするのに十分な程は長くない。ホモ二官能性でチオール反応性のPEG(ビス−マレイミド−dPEG)は、Quanta Biodesign Ltdから購入することができる。カタログは、3個又は11個のいずれかのエチレングリコール単位を有する変形を含むが、別の代替物が、要求に応じて利用可能である。適した長さのリンカーは、PEGによって接続された2つのIgG Fc結合ドメインが同じ抗体に優先的に結合しないが、2つの別々の抗体に結合する場合に見出された。それにより、抗体及びPEGコンジュゲートIgG Fc結合ドメインのネットワークが可能となる。
