我们报道了一种磁镊子的发展,它可以通过在水平面上施加皮牛顿(pN)尺度的力来微操作单个DNA分子。实验得到的力延伸数据显示了DNA系绳延伸变化的高分辨率检测:力的变化约为0.5 pN,延伸变化<10 nm。我们使用多种正交技术校准我们的仪器,包括良好表征的DNA过度拉伸过渡。我们还量化了力和拉伸测量的可重复性,并提供了在不同盐条件下过度拉伸转变行为的数据。详细描述了设计和实验方案,这应该能够直接复制镊子。
We report the development of a magnetic tweezers that can be used to micromanipulate single DNA molecules by applying picoNewton (pN)-scale forces in the horizontal plane. The resulting force–extension data from our experiments show high-resolution detection of changes in the DNA tether’s extension: ~0.5 pN in the force and <10 nm change in extension. We calibrate our instrument using multiple orthogonal techniques including the well-characterized DNA overstretching transition. We also quantify the repeatability of force and extension measurements, and present data on the behavior of the overstretching transition under varying salt conditions. The design and experimental protocols are described in detail, which should enable straightforward reproduction of the tweezers.
