DNA condensation and redissolution: Interaction between overcharged DNA molecules
The effective DNA-DNA interaction force is calculated by computer simulations with explicit tetravalent counterions and monovalent salt. For overcharged DNA molecules, the interaction force shows a double-minimum structure. The positions and depths of these minima are regulated by the counterion density in the bulk. Using two-dimensional lattice sum and free energy perturbation theories, the co...

متن کاملEthanol induces condensation of single DNA molecules
As a widely used precipitation agent for DNA extraction, ethanol is used to induce single molecule DNA condensation. This process is studied with force-measuring magnetic tweezers and atomic force microscopy (AFM). Our experiments provide direct evidence of the metastable intermediate racquet states in DNA collapse induced by ethanol. The measured condensing force is less than 0.2 pN even at 50...

متن کاملCisplatin induces loop structures and condensation of single DNA molecules
Structural properties of single lambda DNA treated with anti-cancer drug cisplatin were studied with magnetic tweezers and AFM. Under the effect of low-concentration cisplatin, the DNA became more flexible, with the persistence length decreased significantly from approximately 52 to 15 nm. At a high drug concentration, a DNA condensation phenomenon was observed. Based on experimental results fr...
