aSequences of the two complementary strands are shown in the 5′ → 3′ direction. The recognition motif TAATA/TATTA is underlined. The positions for the phosphorothioate modification are indicated with ‘ps’.
bFor the concentrations of Na+, 50 mM from the sodium phosphate buffer should be added to the values.
cAverage values and standard deviations from triplicate experiments are shown.
dHeat release was too small to be analyzed.
