FK−506カルバメート誘導体の調製
FK−506エステル誘導体の調製
FK−506カルバメート前処理溶液の調製
FK−506エステル0.45mg/mLを含む貯蔵溶液を、2つの工程により調製した。1)FK−506カルバメート4mgをメタノール2mLに溶解した。次いで溶解したFK−506カルバメートを、プロテアーゼを含まないウシ血清アルブミン30mg/mL、MgCl2 0.126mg/mL、エチレングリコール0.03mL/mL、PIPES 1.5ナトリウム塩35.14mg/mL、NaCl 50mg/mL及びβ−gal突然変異タンパク質(不活性化βガラクトシダーゼ)、pH6.5を含む緩衝液で1:4.5に希釈して、貯蔵溶液を作製した。次いでこの貯蔵溶液を、FKカルバメート2.7μg/mLを含むように脱イオン水で希釈して、実際に使用できる前処理溶液を作製した。
モノクローナル抗FK−506抗体を、標準的なSMCC(スクシンイミジルトランス−4−(N−マレイミジルメチル)シクロヘキサン−1−カルボキシレート)リンカーを用いて、βガラクトシダーゼに接合した。この実際に使用できる抗体接合体溶液は、抗FK−506抗体−βガラクトシダーゼ接合体約7.5μg/mL、プロテアーゼを含まないウシ血清アルブミン30mg/mL、MgCl2 0.126mg/mL、エチレングリコール0.03mL/mL、PIPES 1.5ナトリウム塩35.14mg/mL、NaCl 50mg/mL及びβ−gal突然変異タンパク質(不活性化βガラクトシダーゼ)、pH6.5を含んだ。
FK−506クロム粒子(イムノアッセイの固相)を、FK506−BGG(ウシガンマグロブリン)−デキストラン接合体を作製し、クロム粒子を含むスラリーを調製し、次いでコーティングされた粒子を錠剤化することによって製造した。各々のFK−506錠剤は、FK−506クロムスラリー約2mg、30%ウシ血清アルブミン(BSA)10.5mg、トレハロース二水化物30.4mg及びカーボワックス100μm 3.6mgを含む。
前処理試薬として役立つラパマイシンをまた調製して、FK−506カルバメートと比較した。最終的に実際に使用できる溶液は、ラパマイシン2.7μg/mLをFK−506カルバメートの代わりに用いた以外はFK−506カルバメートの実際に使用できる溶液と同じ成分及び濃度を有した。
FK506アッセイ
FK506の測定は、ACMIAとして公知であり、そして以前の特許(US 5147529、US 5128103、US5158871、US4661408、US 5151348、US 5302532、US 5422284、US 5447870、US 5434051)に記載されたアッセイフォーマットを使用した。FK506方法の原理及び操作は次の通りであった。本発明に記載されたFK506カルバメートを含む前処理試薬を、Dimension(登録商標)化学RxL/HM機器の反応容器に添加した。次に、FK506を含む全血35μLを添加した。この全血を超音波サンプルプローブと最初に混合することによって、この全血を標準カップから採取した。このFK506カルバメート前処理溶液との全血サンプルの混合により、全血を確実に溶解し、そしてFK506カルバメート分子によって、FK506分子に結合したタンパク質をその結合部位から確実に置換させた。従って解放されたFK506分子は、この反応混合物中で抗FK506抗体に接近可能であった。次に、抗FK506抗体−βガラクトシダーゼ接合体(80μL)を添加し、そしてサンプル中でFK506と反応させた。固定されたFK506−BGG(ウシγグロブリン)−デキストランを含むクロム粒子(75μL)を添加し、そして未反応の接合体を結合させた。このFK506に結合した抗FK506抗体−βガラクトシダーゼ接合体はクロムに結合せず上清に残留し、上記の反応混合物に磁場を印加して溶液とクロム粒子とを分離した。このFK506に結合した接合体を、上清を反応容器から測光用キュベットに移し、そしてクロロフェノールレッド−β−D−ガラクトピラノシド(CPRG)の存在下でこの接合体の酵素的速度(enzymatic rate)を測定することによって検出した。この速度を、577nm及び700nmの二色で(bichromatically)測定した。この方法の図解を、以下の図に与える。FK506カルバメートで前処理をした場合としなかった場合を比較して図1のように代表的な校正曲線で示される。
異なる前処理措置の比較
FK506 0、5、10、20及び30ng/mLを含むFK506標準液を測定するために、FK506カルバメート、ラパマイシン又は前処理希釈液を用いて、DIMENSION(登録商標)アッセイ用の前処理溶液を作製した。別のセットのFK506標準液をまた、Syva EMIT(登録商標)前処理溶液で処理した。(サンプル200μLをメタノール200μLで抽出し、次いで混合物中のタンパク質を、硫酸銅溶液50μLで沈殿させた。遠心分離した上清をサンプルとして用いた。)Syva EMIT(登録商標)試薬で処理されなかった標準液を、FK506カルバメート、ラパマイシン又は単に前処理希釈液で各々前処理し、そしてACMIAアッセイを用いてDIMENSION(登録商標)臨床化学分析機器で分析した。Syva EMIT(登録商標)試薬で前処理された標準液を、前処理溶液として前処理希釈液のみを含む試薬カートリッジを用いてDIMENSION(登録商標)機器でACMIAアッセイによって試験した。以下の表は、これらの前処理アプローチを試験することによって得られた結果を示す。
