WebCounterions are important constituents for the structure and function of nucleic acids. Using 7 Li and 133 Cs nuclear magnetic resonance (NMR) spectroscopy, we investigated how ionic radii affect the behavior of counterions around DNA through diffusion measurements of Li + and Cs + ions around a 15-bp DNA duplex. Together with our previous data on 23 Na + … WebAdditionally, peak E and peak A velocities were defined. Interobserver repeatability of VE-CMR was evaluated. By Doppler, MVAs ranged from 0.87 to 4.49 cm 2; by CMR, 0.91 to 2.70 cm 2 correlating well between modalities (r = 0.86). The correlation coefficient for peak E and peak A between modalities was 0.81 and 0.89, respectively.
