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.
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。
