蛋白质-核酸相互作用的荧光和基于作用力的单分子研究继续为DNA和RNA加工的许多方面提供关键的见解。由于单分子分析本质上是低通量的,获得统计上相关的数据集仍然是一个重大挑战。此外,大多数基于荧光的单分子粒子跟踪分析仅限于观察低纳摩尔范围内的荧光蛋白质,因为在较高的荧光团浓度下,虚假背景信号占主导地位。这些技术限制传统上限制了可以通过单分子方法解决的问题的类型。在这篇综述中,我们描述了高通量和高浓度单分子生化研究的新方法。最后,我们讨论了单分子生物学家面临的突出挑战,以及如何解决这些挑战,以进一步接近细胞的生化复杂性。
Fluorescence and force-based single-molecule studies of protein-nucleic acid interactions continue to shed critical insights into many aspects of DNA and RNA processing. As single-molecule assays are inherently low-throughput, obtaining statistically relevant datasets remains a major challenge. Additionally, most fluorescence-based single-molecule particle-tracking assays are limited to observing fluorescent proteins that are in the low-nanomolar range, as spurious background signals predominate at higher fluorophore concentrations. These technical limitations have traditionally limited the types of questions that could be addressed via single-molecule methods. In this review, we describe new approaches for high-throughput and high-concentration single-molecule biochemical studies. We conclude with a discussion of outstanding challenges for the single-molecule biologist and how these challenges can be tackled to further approach the biochemical complexity of the cell.
