Erratum: Peptide nucleic acid and delivery to human mitochondria

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.
