Figure 9: 1H NMR spectra of VK1 in the presence of different cations.
From: A tetrahelical DNA fold adopted by tandem repeats of alternating GGG and GCG tracts
The spectra were recorded at 2.0 mM oligonucleotide concentration per strand, pH 6, 0 °C and 100 mM cation concentrations on an 800 MHz spectrometer.
