Targeting a viral DNA sequence with a deoxyribozyme in a preparative scale.

In this report, catalytic activity of an oxidizing DNA-cleaving deoxyribozyme, F-8(X), was comprehensively inspected in semi-preparative (10 μM substrate) scale. A 60 nucleotides long synthetic DNA sequence was selected as the target DNA for this study. The DNA sequence was originated from a single stranded DNA virus. Investigations revealed high yield in the presence of optimal concentration of oxidizing agents. The optimal conditions have been applied for scale-up of the reaction to preparative (40 μM substrate) and multi-turnover reactions to achieve highest amount of product in a cost-, time- and labor-effective manner. Such a comprehensive analysis of a deoxyribozyme's activity in semi-preparative scale provides a platform for expanded applications of DNA catalysts as a tool in chemical biology.
