In the above article, the authors inadvertently used the incorrect extinction coefficient of 8900 M⁻¹ cm⁻¹ for calculating concentrations of PNAs and their conjugates at 260 nm. Measurements should have been made using 97 900 M⁻¹ cm⁻¹. Consequently, all concentrations are effectively 11–fold more dilute than reported.
