The comet assay – from toy to tool
Frontiers in Genetics, 2015 The comet assay is nowadays the most common method for measuring DNA damage and repair in single cells. It is based on the microelectrophoretic study published by Ostling and Johanson (1984) and was developed by Singh and coworkers (1988) to a versatile ...

Comet Assay in Cancer Chemoprevention
, 2016 The comet assay can be useful in monitoring DNA damage in single cells caused by exposure to genotoxic agents, such as those causing air, water, and soil pollution (e.g., pesticides, dioxins, electromagnetic fields) and chemo- and radiotherapy in cancer patients, or in the assessment of genoprotective effects of chemopreventive molecules. Therefore, it

Relationship between CpG and non-CpG DNA methylation in human lymphocytes assessed with comet assay [PDF]
The Ukrainian Biochemical JournalTissue-specific DNA methylation plays an important role in the regulation of many functional processes. The methylation level in single cells can be assessed using the comet assay (single-cell gel electrophoresis), a simple and cost-effective technique ...

The Effect of Obstructive Sleep Apnea on DNA Damage and Oxidative Stress [PDF]
Clinical and Experimental Otorhinolaryngology, 2013 ObjectivesObstructive sleep apnea syndrome (OSAS) is associated with repeated hypoxia and re-oxygenation. This characteristic of OSAS may cause oxidative stress and DNA damage.

The comet assay: topical issues [PDF]
Mutagenesis, 2008 The comet assay is a versatile and sensitive method for measuring single- and double-strand breaks in DNA. The mechanism of formation of comets (under neutral or alkaline conditions) is best understood by analogy with nucleoids, in which relaxation of DNA supercoiling in a structural loop of DNA by a single DNA break releases that loop to extend into a
