この開示の全体を通して、あらゆる文献、特許文献および公表された特許明細書は、引用を特定することにより参照される。これらの文献、特許文献および公表された特許明細書は、本開示中で援用することにより本発明に関する技術分野の水準を十分に記載する。
本発明の実施は、特に示すことがない限り、免疫学、分子生物学、微生物学、細胞生物学および組み換えDNAの従来技術を用い、それらは当該技術分野の範囲内である。例えば、Sambrook, Fritsch and Maniatis, Molecular Cloning: A Laboratory Manual, 2nd edition (1989); Current Protocols In Molecular Biology (F. M. Ausubel et al. eds., (1987)); the series Methods In Enzymology (Academic Press, Inc.): Pcr 2: A Practical Approach (M.J. MacPherson, B.D. Hames and G.R. Taylor eds. (1995)), Harlow and Lane, eds. (1988) ANTIBODIES, A LABORATORY MANUAL And ANIMAL CELL CULTURE (R.I. Freshney, ed. (1987))を参照。
AAVベクターの力価をゲノムコピー数(ミリリットルあたりのゲノム粒子)により測定することができる。ゲノム粒子濃度は、以前報告されたように、ベクターDNAのTaqman(登録商標)PCRを基にしてもよい(Clark et al. (1999) Hum. Gene Ther. 10:1031 1039; Veldwijk et al. (2002) Mol. Ther. 6:272 278)。簡単に説明すると、AAVベクターをDNAse溶液で処理してウイルスDNAの正確な測定を妨げうる混入DNAを除去する。次いで、AAVベクターを外被消化緩衝液(50mM Tris−HCl pH8.0、1.0mM EDTA、0.5% SDS、1.0mg/ml プロテイナーゼK)を用いて50℃で1時間処理してベクターDNAを遊離させる。DNAサンプルを、プロモーター領域、導入遺伝子、またはポリA配列のごときベクターDNAにおける特異的な配列にアニールするプライマーを用いてポリメラーゼ連鎖反応(PCR)にかける。次に、PCRの結果を、Perkin Elmer−Applied Biosystems(カリフォルニア州のフォスターシティー)Prism 7700 Sequence Detector Systemにより提供されるごときReal time Taqman(登録商標)ソフトウェアにより定量化する。
酸スフィンゴミエリナーゼ欠損マウス(ASMKO)(K. Horinouchi et al., Nat. Genet. 10 (1995), pp. 288-292)を以下の通りに処置した:
