Broad spectrum detection of DNA damage by Repair Assisted Damage Detection (RADD) [PDF]

DNA Repair, 2018
Environmental exposures, reactive by-products of cellular metabolism, and spontaneous deamination events result in a spectrum of DNA adducts that if un-repaired threaten genomic integrity by inducing mutations, increasing instability, and contributing to the initiation and progression of cancer.
