( Data for the AT-rich single-stranded oligonucleotide 3U is shown with the best fit to Equation (), with values of = 37.5 ± 1.8 s and = 3.9 ± 0.5 μM. () The data for the GC-rich single-stranded oligonucleotide 4U did not reach saturation and exhibited a linear rather than hyperbolic relationship, hence is shown with the best fit to a linear equation
