The Comet Assay in Marine Animals

Comet assay is a quick and versatile technique for assessing DNA damage in individual cells. It allows the detection of DNA single- and double-strand breaks, as well as the presence of alkali-labile sites and cross-links. Here we describe the protocols for the single-cell gel electrophoresis (Comet) assay in its alkaline (pH > 13), mild alkaline (pH = 12.1), and neutral (pH = 8) versions, when applied in marine animals.
