ポリマー基材が官能基を含み、前記官能基がフリーラジカルリガンドに共有結合して、表面反応性基を形成しており、さらに、

BSA容量の測定
溶液1の調製(50mMトリス/HCl、pH8.8)
12.1gのトリス(ヒドロキシメチル)アミノメタン(フィッシャーサイエンティフィック)を2Lの容量フラスコに入れた。次いで、0.01NのHCl溶液(フィッシャーサイエンティフィック)を入れて、2リットルの印までフラスコを満たした。容量フラスコに蓋をした後でこの内容物を振とうした。この溶液を5分間静置し、溶液の体積を再度チェックした。2Lの印まで体積を調節するために追加のHClを入れた。pHは8.8±0.05であると測定された。この溶液をラベルし、4℃に冷却した。
0.806gのBSAがガラスジャーに秤量され、403gの溶液1に添加された。この内容物は穏やかに混合されて溶解させられた。BSAの完全な溶解を確実にするためにこの溶液を0.5時間静置した。
空気を捕捉するのを妨げるために、1mlのDI水がクロマトグラフィーカラムにゆっくりと添加された。実施例3もしくは4のスラリー溶液をカラムに入れた。カラムに1mlの樹脂が量り入れられた。樹脂上方の溶液1〜2cm以外の全てを除去するために穏やかな真空が適用された。樹脂のレベルが1mlの印より下になったら、さらなる樹脂スラリーが追加の真空をかけつつ添加された。樹脂床は決して空気に曝されなかった。充填された1mlの樹脂は約10mlのDI水ですすがれ、スラリー溶液を置き換え、水のレベルが充填床の1〜2cm上方になるまで液体が排出された。次いで、充填された1mlの樹脂は10mlの溶液1でフラッシュされた。真空によって溶液1はカラムから除去され、空気は1分間にわたってカラムを通して吸引された。湿潤ケーキを収容するディスポーサブルカラムはマニホルドから取り外された。
BSA結合容量は18時間のインキュベーション後のろ過された上澄BSA溶液の278nmUV吸光度から決定された。溶液1を満たしたキュベットがUV分光計をゼロにするのに使用された。278nmでの吸光度は全てのサンプル、標準溶液および対照サンプルについて測定された(GEへスルケアのQセファロース商標ファストフローイオン交換樹脂)。
機械式スターラーを備えた三ツ口丸底フラスコに、湿潤ケーキとして15gのエポキシド含有ビーズ(60μmポリGMA−GlyDMAビーズグリシジルメタクリラート(GMA)およびグリセロール−1,3−ジメタクリラート(GlyDMA)、米国特許出願公開第2007−0066761A1号の実施例25に開示されたのと同様の手順によって製造)を入れて、次いで、18mLの水を添加してスラリーを形成した。tert−ブチルヒドロペルオキシド(tBHP、シグマ−アルドリッチ)およびトリエチルアミン(Et3N)(シグマ−アルドリッチ)がこのスラリーに添加され、反応混合物は室温でN2雰囲気下で一晩攪拌された。ビーズがろ別され、水ですすがれた。得られた物質は水中のスラリーとして貯蔵された。
テフロン(登録商標)攪拌パドルを備えた250mlの反応フラスコ内に実施例1のエポキシド含有ビーズ(GMA/GLYDMAコポリマー)湿潤ケーキ25gを入れ、オーバーヘッドスターラーを145RPMにセットした。30gのミリQ水、0.5gの4ヒドロキシtempo(アルドリッチ、ロット77997KJ)、0.08gのトリブチルアミン(アルドリッチ、ロットA0256662)および1.8gの37%過酢酸を反応器に添加した。この反応器を50℃で1時間加熱し、次いで50℃で18時間保持した。室温に冷却し、350mlのフリット付きガラス漏斗においてビーズを単離し、1リットルのミリQ水ですすいだ。
機械式スターラーを備えた三ツ口丸底フラスコに10gのペルオキシド改変ビーズ(実施例1で得られた)、13.6gのAMPTAC(シグマ−アルドリッチ)および10mLの水が入れられた。この溶液を15分間N2でパージした。この反応混合物を85℃に加熱し、N2下で一晩攪拌した。このビーズはろ別され、水ですすがれた。得られた材料は水中のスラリーとして貯蔵された。BSA容量162mg/ml。
テフロン(登録商標)攪拌パドルを備えた250mlの反応フラスコ内に実施例2の生成物湿潤ケーキ25gを入れ、オーバーヘッドスターラーを145RPMにセットした。攪拌しつつ、6gの75%(3−アクリルアミドプロピル)トリメチルアンモニウムクロリド(アルドリッチ、ロット#02523MH)を反応フラスコに入れた。次いで、0.12gの過硫酸アンモニウム(アルドリッチ、ロット#A0264270)および13.6gのミリQ水を反応器に添加した。この混合物を室温で1時間攪拌した。この反応器を80℃で1時間加熱し、次いで、この反応器を80℃で5時間保持した。50℃に冷却し、56mlの1NaOHをゆっくりと(5分間にわたって)反応器に添加した。1時間50℃で保持した。次いで、反応器を室温に冷却した。350mlのフリット付きガラス漏斗においてビーズを単離し、3リットルのミリQ水ですすいだ。BSA容量74mg/ml。
