Single-Cell Gel Electrophoresis (Comet) Assay in Nano-genotoxicology

The Comet assay, or single-cell gel electrophoresis assay, is an easy and simple yet reliable method to evaluate DNA damage in cells. Under the alkaline conditions of this method, DNA strand breaks and alkaline-labile sites are detected. Here we describe the alkaline version of the Comet assay with applications in testing nanoparticles.
