Probing Physical Properties of a DNA- Protein Complex Using Nanofluidic Channels
Journal article, 2014
A method to investigate physical properties of a DNA-protein complex in solution is demonstrated. By using tapered nanochannels and lipid passivation the persistence length of a RecA filament formed on double-stranded DNA is determined to 1.15 μm, in agreement with the literature, without attaching protein or DNA to any handles or surfaces. © 2014 WILEY-VCH Verlag GmbH and Co.
