Melting mapping in nanochannels

Summary, in English

We demonstrate direct visualization of melting mapping of DNA stretched in nanoscale channels[1] using standard staining methods and epifluorescence microscopy to gain information on the local AT/GC ratio along large DNA molecules. Our development opens up a novel route to mapping of large-scale genomic variations.
