Measuring DNA modifications with the comet assay: a compendium of protocols
Collins, Andrew; Moller, Peter; Gajski, Goran; Vodenkova, Sona; Abdulwahed, Abdulhadi; Anderson, Diana; Bankoglu, Ezgi Eyluel; Bonassi, StefanoThe comet assay is a versatile method to detect nuclear DNA damage in individual eukaryotic cells, from yeast to human. The types of damage detected encompass DNA strand breaks and alkali-labile sites (e.g., apurinic/apyrimidinic sites), alkylated and oxidized nucleobases, DNA-DNA crosslinks, UV-induced cyclobutane pyrimidine dimers and some chemically induced DNA adducts. Depending on the specimen type, there ...
Inter-laboratory variation in DNA damage using a standard comet assay protocol
Forchhammer, Lykke; Ersson, Clara; Loft, Steffen; Moller, Lennart; Godschalk, Roger W. L.; van Schooten, Frederik J; Jones, George D. D.There are substantial inter-laboratory variations in the levels of DNA damage measured by the comet assay. The aim of this study was to investigate whether adherence to a standard comet assay protocol would reduce inter-laboratory variation in reported values of DNA damage. Fourteen laboratories determined the baseline level of DNA strand breaks (SBs)/alkaline labile sites and formamidopyrimidine DNA glycosylas...
