Telomeric G-Quadruplexes: From Human to Tetrahymena Repeats

Figure 2

CD spectra of oligonucleotides used in this study in a 25 mM modified Britton-Robinson buffer (pH 7.0) in the presence of 50 mM KCl (a–c) and 50 mM NaCl (d–f). The HTR and THR spectra are shown in red and magenta, respectively. Each DNA sample was annealed at 95°C for 5 min and then allowed to cool for ~1 h to the initial temperature at which the sample was kept at the beginning of the measurement [14].
