Analysis of the behavior of NH4+ ions within the ion atmosphere. (A, B) Diffusion coefficients of 15NH4+ ions and 15N formamide in solutions of the 15-bp DNA (Panel B) and in solutions of the Antp HD (Panel A). Diffusion coefficients of the DNA and the protein are also plotted. (C) Competition between 15NH4+ and K+ ions for the ion atmosphere around DNA. The DNA concentration was 1.7 mM in this experiment on the ionic competition. Error bars represent the standard errors of the means for at least 3 replicates.
