Effect of different counter-cations on iCD-DNA formation and stability.

<p>(a) Circular dichroism spectra of 20 μM d(C₂G₄)₇ in various buffered salt solutions at pH 5.2. The spectra on the left were taken immediately following dilution; the spectra on the right were taken 14 hrs following dilution and further incubation in the various buffers at 37° C. (b) CD spectra of 20 μM d(C₂G₄)₇ diluted into different buffers at pH 5.2. All CD measurements were taken at 22°C.
