Prolonged DNA hydrolysis in water: A study on DNA stability

This work provides a protocol for the in vitro production of damaged DNA samples. In particular, heat-mediated hydrolysis of the samples at 70 degrees C in ultrapure water was performed in 1.7 mL Eppendorf tubes sealed by Parafilm for 0-36 h. The chemical/physical features of the resulting samples are described. After normalization of the qPCR data, these were compared with those obtained from samples treated for 0-10 h in a previous study. (C) 2018 The Authors. Published by Elsevier Inc.
