What is the CometAssay?
The Comet assay, or single cell gel electrophoresis assay, provides a simple and effective method for evaluating DNA damage in cells. The principle of the assay is based upon the ability of denatured, cleaved DNA fragments to migrate out of the nucleoid under the influence of an electric field, whereas undamaged DNA migrates slower and remains within the confines of the nucleoid when a current is applied. Evaluation of the DNA “comet” tail shape and migration pattern allows for assessment of DNA damage. The general Comet assay protocol includes first immobilizing cells in a bed of low melting point agarose, gently lysing the cells, treating cells with neutral or alkali solutions to unwind and denature the DNA as well as hydrolyze sites of damage. DNA is then subjected to electrophoresis and stained with a fluorescent DNA intercalating dye.
