这篇评论是一个实用的指南,有兴趣专门标记内部序列的双链(ds)DNA分子的单分子实验的实验。我们描述了六种标记方法证明在一个单分子的上下文中,并讨论了每种方法的优点和缺点,特别注意的量的专门培训和所需的试剂。通过评估每种方法,根据相关的单分子实验的标准,包括标记产率和兼容性与辅因子,如Mg2+,我们提供了一个简单的参考,选择一个标记方法给定的实验约束。旨在为非专业人士寻求DNA标记挑战的可访问解决方案,概述的方法强调简单性,鲁棒性,适用于非生物学家,并在不同的单分子实验中的实用性。
This review is a practical guide for experimentalists interested in specifically labeling internal sequences on double-stranded (ds) DNA molecules for single-molecule experiments. We describe six labeling approaches demonstrated in a single-molecule context and discuss the merits and drawbacks of each approach with particular attention to the amount of specialized training and reagents required. By evaluating each approach according to criteria relevant to single-molecule experiments, including labeling yield and compatibility with cofactors such as Mg2+, we provide a simple reference for selecting a labeling method for given experimental constraints. Intended for non-specialists seeking accessible solutions to DNA labeling challenges, the approaches outlined emphasize simplicity, robustness, suitability for use by non-biologists, and utility in diverse single-molecule experiments.
