DNA damage has been linked to genomic instability and the progressive breakdown of cellular and organismal homeostasis, leading to the onset of disease and reduced longevity. Insults to DNA from endogenous sources include base deamination, base hydrolysis, base alkylation, and metabolism‐induced oxidative damage that can lead to single‐strand and double‐strand DNA breaks. Alternatively, exposure to environmental pollutants, radiation or ultra‐violet light, can also contribute to exogenously derived DNA damage. We previously validated a novel, high through‐put approach to measure levels of DNA damage in cultured mammalian cells. This new CometChip Platform builds on the classical single cell gel electrophoresis or comet methodology used extensively in environmental toxicology and molecular biology. We asked whether the CometChip Platform could be used to measure DNA damage in …
