Abstract

Plasmids containing a site-specific DNA interstrand cross-link (ICL) are invaluable tools for the investigation of ICL repair pathways at the biochemical and cellular level. We describe a procedure for preparation of plasmid DNA substrates containing a single ICL at a specific site. The procedure is versatile, leads to reliable yields of pure DNA substrate, and is suitable for the incorporation of virtually any type of DNA lesion into plasmids.

摘要

含有位点特异性DNA链间交联(ICL)的质粒是在生化和细胞水平研究ICL修复途径的宝贵工具。我们描述了一种制备在特定位点含有单个ICL的质粒DNA底物的方法。该方法用途广泛,能可靠地获得纯DNA底物,并且几乎适用于将任何类型的DNA损伤掺入质粒中。
