Description
Qは直径30~40μmのクロマトグラフィービーズであり、
Sはスペーサーであり、
Lはアミド結合であり、
XはCOOHであり、n=2~3である。)
QB10%での動的結合容量(DBC)は、60μmよりも大きいビーズサイズを有するIMAC媒体と比較して2倍超であり、好ましくはQB10%は3倍超以上、例えば6倍以上である。
材料および方法
IMACプロトタイプ
1.Excel HPプロトタイプ
・Sepharose High Performanceに結合したLS018819 Excel配位子、アリル含有量170μmole/ml
・Sepharose High Performanceに結合したLS019382 Excel配位子、アリル含有量189μmole/ml
・参照カラム:HiTrap excel、1ml、GE Healthcare
2.デキストランコーティングプロトタイプ
・LS018835AデキストランコーティングIMAC Sepharose High Performance
・参照カラム:LS018835B NaOH処理エポキシ活性化IMAC Sepharose High Performance
HiTrapパッキング方法(GE Healthcare Bio-Sciences AB)に従って、1mlのHiTrapカラムにプロトタイプ樹脂をパッキングした。HiTrapカラムのパッキングには50~60%のスラリー濃度を使用した。
精製ヒスチジンタグ付きマルトース結合タンパク質(MBP-His)および緑色蛍光タンパク質(GFP-His)をカラムに充填することによって、動的結合容量(DBC)を試験した。吸光度を記録し、試料吸光度の10%ブレークスルー(QB10%)での容量を計算した。
17%グリセロール、20mMリン酸ナトリウム、500mM NaCl、pH7.4中のヒスチジン(6)タグ付き緑色蛍光タンパク質(GFP-His)、濃度2.5mg/ml。
大腸菌、20mMリン酸ナトリウム、500mM NaCl、pH7.4中のヒスチジン(6)タグ付き緑色蛍光タンパク質(GFP-His)、濃度約3mg/ml。
結合緩衝液、A:20mMリン酸ナトリウム、500mM NaCl、pH7.4
溶出緩衝液、B:結合緩衝液中の500mMイミダゾール
クロマトグラフィー法
この実験では、Sepharose High Performance(GE Healthcare Bio-Sciences AB)(ビーズサイズ直径34μm)に、欧州特許第2164591B1号明細書に記載されている五座配位子(pentaligand)を結合させた。このビーズは、大きいビーズサイズを有する樹脂と比較して、結合のための表面積を増加させる小さいビーズサイズを有する。ビーズサイズを小さくすると、カラム内の繰り返し結合(オフ-オン事象)の数も増えるはずである。これは、試料適用中の標的タンパク質の漏出を減らすのに有益であり得る。従来のIMAC媒体と比較してわずかに大きい孔径のHigh Performance樹脂もまた、標的タンパク質への接近可能性を高め得る。
ガラスフィルター(p3、6GV)上で、120mlのSepharose HP樹脂を水で洗浄し、水に吸引させた。次いで、7.5mlの蒸留水とともに、120gの吸引された樹脂をジャケット付き反応器に移した。撹拌を開始し、12mlの50%NaOHをスラリーに加えた。スラリーを30分間撹拌し、次いで47℃に加熱し、60mlのAGEを加えた。約18時間後、撹拌を止め、スラリーをガラスフィルターに移した。その後、スラリーを水(1GV×3)、EtOH(1GV×3)、次いで水(1GV×6)で洗浄した。
100g/mlの吸引された乾燥アリル化ゲルを反応反応器に移し、続いて5分間撹拌しながら300mlの水および4.6gの酢酸ナトリウム三水和物を加えた。ゲルの色が濃い暗黄色になるまで、反応混合物に約5mlの臭素を加え、室温で5分間撹拌しながら反応を放置した。反応混合物に約7.8gのギ酸ナトリウムを加え、黄色が消えるまで15分間撹拌しながら反応を放置した。ガラスフィルター(P3)上でゲルを水(10×1GV)で洗浄した。
工程2から得られた100gの臭素化ゲルを反応反応器に移し、150mlのアンモニア溶液を加え、反応混合物を一晩45℃で放置した。ガラスフィルター(P3)上でゲルを10×1GVで洗浄した。
工程3から得られた100gのアミノ化ゲルをアセトン(6×1GV)で洗浄し、反応反応器に移し、100mlのアセトンを加えた。反応混合物に2.9gのDIPEAを加え、5分間撹拌しながら反応を放置した。反応混合物に5.3gのEDTAを加え、混合物を一晩24~28℃で放置した。ゲルをアセトン(3×1GV)、続いて水(3×1GV)で洗浄した。吸引されたゲルを反応器に移し、2M NaOH(1GV)を加えて未反応のEDTAのアクセス(access)を加水分解した。ガラスフィルター(P3)上でゲルを6×1GVで洗浄した。
2つの異なる精製ヒスチジンタグ付きタンパク質(MBP-HisおよびGFP-His)を用いて動的結合容量、DBCを試験し、10%ブレークスルー、QB10%で計算した。弱結合MBP-Hisの損失は、市販のHisTrap excelからは、ほぼ即座に始まったのに対して、Excel HPプロトタイプLS018819では遅延が検出された(図1)。計算されたQB10%は、HisTrap excelについてはLS018819 MBP-His(約5mg)/樹脂(ml)であり、プロトタイプについてはMBP-His(約30mg)/樹脂(ml)であった(図2)。したがって、プロトタイプのQB10%は約6倍優れていた。
ヒスチジンタグ付きタンパク質に対する高容量はまた、1つまたは複数のヒスチジンを含む不純物に対する高容量をもたらし得る。大腸菌溶解物中のGFP-Hisの試料をカラムに加えることによって、最終純度を検討した。不純物が結合するための遊離配位部位を残すために低充填を使用した。イミダゾールを加えずに試料を適用し、イミダゾール勾配により溶出した。還元SDS-PAGEによって溶出ピークを分析した(図5)。図5のレーン1~3の2つの主要なバンドの理由は、GFP-Hisの既知の切断(まだヒスチジンタグが残っている)によって説明することができると考えられる。2つの樹脂の最終純度は同等であった。
デキストランコーティングの目的は、ヒスチジンタグ付きタンパク質の結合を維持しながら、1つまたは複数のヒスチジンを含む不純物の多点結合を防ぐことであった。(New dextran-coated immobilized metal ion affinity chromatography matrices for prevention of undesired multipoint adsorptions,Journal of Chromatography A,915(2001)97-106.)この場合、四座のIMAC Sepharose High Performance(GE Healthcare Bio-Sciences AB)を使用したが、結果は五座樹脂にも当てはまるはずである。
ガラスフィルター上で、ゲル(IMAC Sepharose High Performance)のスラリー約100mlを水(5×1GV)で洗浄した。次いでゲルを吸引乾燥し、エポキシ活性化のために50gを250mlの三口フラスコに量り入れた。次いでフラスコに12mlの水を加え、撹拌しながら28℃に加熱し始めた。撹拌中に8mlの50%NaOHを加え、次いでスラリーを28℃で約10分間撹拌し、その後エピクロロヒドリン(12.5ml)を加え、次いで3.5時間撹拌した。次いで、ガラスフィルター上でゲルを水(6×1GV)で洗浄した。
約3時間回転撹拌しながら、35.2mlの水を入れたDuranフラスコ内で、8gのデキストランTF(10%Dx TF)を溶解した。次いで、上記から得られた40gの排出されたエポキシ活性化ゲルをフラスコに加え、その後スラリーを40℃に加熱し、60分間回転撹拌した。次いで、フラスコに4.8mlの50%NaOHおよび0.1gのNaBH4を加え、その後40℃で一晩回転撹拌した。ゲルを水(10×1GV)で洗浄した。
50mlのFalconチューブに、8.8mlの蒸留水とともに、上記から得られた10gの排出されたエポキシ活性化ゲルを加え、均一なスラリーになるまで振盪した。次いで、チューブに1.2mlの50%NaOHおよび0.05gのNaBH4を加えた。その後チューブを振盪台の上に置き、40℃に加熱し、一晩振盪した。
上記のように、エポキシ活性化IMAC Sepharose High Performanceに約10%のデキストラン層を加えた。試料は大腸菌溶解物中のGFP-Hisであり、イミダゾール勾配を用いて溶出を行った。クロマトグラムによると、参照では、280nmでの吸光度を有するプレピークが検出されたが、デキストランコーティングプロトタイプLS018835A(図示せず)では検出されなかった。プレピークは490nmでの吸光度(GFP-Hisに特異的)を欠き、これは混入物の含有を示すものであった。還元SDS-PAGEによって溶出試料を分析した(図6)。結果は、デキストランコーティング樹脂の方が純度が高いことを示しているが、エポキシ活性化樹脂LS018835Bも参照よりも高い純度を有した。したがって、両プロトタイプは、参照よりも明らかに優れた純度特性を有した。
