2つのTSK Super SW2000カラム(300×4.6mm)及び1つのTSK Super ガードカラム(35×4.6mm)(TOSOH BIOSEP)を用いて、ゲル排除クロマトグラフィーを実行する。UV域232nmにおいて、吸光光度分析法により、検出を行なう。移動相は、0.1M酢酸アンモニウムである。注入された量は5μlである。
CTA−SAX方法により、HPLCのモニタリングを実行する。使用したカラムは、45℃で、0.2ml/分にて、4時間、水/メタノール(68/32)v/vの混合物中の、1mM セチルトリメチルアンモニウムリン酸水素溶液の浸透により、セチルトリメチルアンモニウムがその上に吸着された、3μm粒子のHypersil BDS(150×2.1mm)である。
45℃で、2ml/分にて、4時間、水/メタノール(68/32)v/vの混合物中の、1mM セチルトリメチルアンモニウムリン酸水素溶液の浸透により、セチルトリメチルアンモニウム鎖がその上にグラフト化された、5μm粒子のHypersil BDSカラム(250×20mm)上のクロマトグラフィー。室温で分離を実行する。使用される溶出勾配:溶媒Aは、HClを添加することによってpHを2.5にした水である。溶媒Bは、pH2.5に調節された、2N NaCl溶液である。
ヘパラナーゼ1を用いたヘパリンのATIIIの親和性部位の開裂によって、六糖ΔIs−IIaid−IIsglu(六糖iso ATIII)を得る。ヘパラナーゼ1を用いたヘパリンの解重合は、内因性溶解性であり:それらの非還元末端が不飽和のオリゴ糖の混合物をもたらす。反応終了後、二糖、四糖及び六糖の混合物を得る。ヘパリンの最も硫酸化された全領域を開裂し、二糖及び四糖へ転換する。アセチル化された部分のみが、六糖形態を維持し、特に、−GlcNS(6S又は6OH)−IdoA−GlcNAc(6S又は6OH)−GlcA−GlcNS(3S又は3OH,6S又は6OH)−型の鎖を維持する。
ヘパラナーゼの阻害能力に関するHexa Iso ATIII関連の評価を、次のように実行した。
まず、ヘパラナーゼアッセイを、この研究の必要性に応じて最適化した。実用的な理由から、分解アッセイにおけるインキュベーション時間を18時間の時点で確立した。標識化の効率性及びヘパラン硫酸(プロテオグリカン)の含有量に応じて、ヘパラン硫酸(プロテオグリカン)総計数を、約2200cpm/試料に固定し、ヘパラン硫酸(プロテオグリカン)の1バッチで全アッセイの実行を可能にした。図1aは、天然試料のTSK4000ゲル浸透クロマトグラフィーを示す。図1bは、その試料の分子分布における、ヘパラナーゼ誘起シフトを示す。次いで、ヘパラン硫酸プロテオグリカン約80%を分解できるヘパラナーゼ量を決定する(ヘパラン硫酸プロテオグリカン約35%及びコンドロイチン/デルマタン硫酸プロテオグリカン約65%を含有する試料)。従って、10−80%の範囲の分解は、比較的直線状であり、阻害剤の効果の決定において許容される。図1cは、97.3%の阻害で、ヘパラナーゼ活性の1μg/mlの未分画ヘパリン(UFH)の効果を示す。
フォンダパリヌクスを分解する能力により、ヘパラナーゼの活性を決定する。フォンダパリヌクスの濃度を、その抗Xa因子の活性によって決定する。
ヘパラナーゼは、Sanofi−Synthelabo(Labege、フランス)によって、調製される。
a)反応混合物
酢酸ナトリウムバッファ(0.2M、pH4.2)50μlを、フォンダパリヌクス(0.45μg/ml)50μl及びヘパラナーゼ溶液59μlと混合する。混合物を37℃で、1時間、インキュベートし、次いで95℃で、5分間、インキュベートする。pHは、2.4から7となる。次いで、反応混合物100μlを、175mM NaCl及び75mM EDTAを含有するpH14の50mMトリスバッファ50μlのと混合する。
段階a)で得た溶液100μlを、AT(0.5μg/ml)100μlと混合する。この混合物を37℃で、2分間、維持し、次いで、Xa因子(7nkat/ml)100μlを添加する。その混合物を37℃で、2分間、維持し、発色基質(参照番号:S2222)(1mM)100μlを添加する。この混合物を37℃で、2分間、維持し、次いで酢酸(50%)100μlを添加する。
