次の手順に従い、溶出緩衝液1を調製した。Milli−Qグレード水(1.0kg)およびL−ヒスチジン(32.0g)を合わせ、室温で10分間撹拌した。次に混合物を40±5℃に加熱して、水中でL−ヒスチジンを完全に溶解させた。次いで加熱を止め、混合物に次の構成成分を添加した:D−マンニトール(48.02g)、1%Tween80希釈標準溶液(16.02g)、D−ソルビトール(32.03g)、100mM MgCl2・6H2O希釈標準溶液(32.0g)、KH2PO4(0.38g)、Na2HPO4・7H2O(4.36g)、KCl(0.32g)およびNaCl(12.80g)。構成成分をよく混合し、さらなるMilli−Qグレード水を添加して1.6kgの緩衝液を得た。
次の手順に従い、溶出緩衝液2を調製した。Milli−Qグレード水(1.0kg)、スクロース(64.0g)、Tween80(0.81g)、100mM MgCl2・6H2O希釈標準溶液(32.0g)、KH2PO4(0.38g)、Na2HPO4・7H2O(4.35g)、KCl(0.32g)およびNaCl(12.80g)を合わせた。構成成分をよく混合し、さらなるMilli−Qグレード水を添加して、1.6kgの緩衝液を得た。
次の手順に従い、実施例2で示される緩衝液の2倍の濃縮処方の溶出緩衝液1を調製した。Milli−Qグレード水(61.78g)およびL−ヒスチジン(4.00g)を合わせ、室温で10分間撹拌した。次に、混合物を40℃に27分間加熱し、水中でL−ヒスチジンを完全に溶解させた。次いで加熱を止め、混合物に次の構成成分を添加した:D−マンニトール(6.00g)、1%Tween80希釈標準溶液(2.02g)、D−ソルビトール(4.00g)、100mM MgCl2・6H2O希釈標準溶液(4.01g)、KH2PO4(0.024g)、Na2HPO4・7H2O(0.27g)、KCl(0.021g)およびNaCl(0.81g)。構成成分をよく混合し、さらなるMilli−Qグレード水を添加して、100gの緩衝液を得た。
次の手順に従い、実施例3で示される緩衝液の2倍の濃縮処方の溶出緩衝液2を調製した。Milli−Qグレード水(60.0g)、スクロース(8.00g)、1%Tween80希釈標準溶液(10.0g)、100mM MgCl2・6H2O希釈標準溶液(4.01g)、KH2PO4(0.024g)、Na2HPO4・7H2O(0.27g)、KCl(0.021g)およびNaCl(0.80g)を合わせた。構成成分をよく混合し、さらなるMilli−Qグレード水を添加して100gの緩衝液を生成させた。
リン酸緩衝食塩水(PBS)中2.76x1014個のレオウイルス粒子を与えることにより、対照ウイルス標品(対照標品)を調製した。溶出緩衝液1中で2.76x1014個のレオウイルス粒子を与えることにより、ウイルス標品1を調製した。溶出緩衝液2中で2.76x1014個のレオウイルス粒子を与えることにより、ウイルス標品2を調製した。
実施例6で調製したウイルス標品(対照標品、ウイルス標品1およびウイルス標品2)をそれぞれ個々にゲル浸透クロマトグラフィーカラム上に載せた。対照標品、ウイルス標品1およびウイルス標品2をPBS、緩衝液処方1および緩衝液処方2でそれぞれ溶出した。個々の実験からの平均データを表1および2で示す。
