Determination of the persistence length of ssRNA at varying [Mg2+]. Estimators of Inline graphic obtained experimentally were compared with the expected Inline graphic profiles for different values of P (0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4 and 1.5 nm from top to bottom) using Equation 7 and Equation 10. Red (green) points are the experimental estimators Inline graphic at a pulling rate of 12.5 (1.8) pN/s. Blue (magenta) points are the experimental estimators of Inline graphic at a pulling rate of 12.5 (1.8) pN/s. Light blue lines are the Inline graphic profiles for values of m not matched, and black lines are the experimental estimators of Beff(f) that match the experiments. Application of the method for experiments done at 0.01 mM [Mg2+] (A), 0.1 mM [Mg2+] (B), 0.5 mM [Mg2+] (C), 1 mM [Mg2+] (D), 4 mM [Mg2+] (E) and 10 mM [Mg2+] (F).
