How to interpret comet assay results
Webto ensure that only true single comets were used in the final calculation. During the standard alkaline comet assay, nuclei may end up in close proximity to each other, or overlapping, causing multiple comets to be identified as a single object (Figure 3, seen with CC2 and CC3). However, these objects demonstrate criteria that are different Web7 apr. 2024 · The in vivo comet assay is used to evaluate the genotoxic potential of compounds by detecting DNA strand breaks in cells isolated from animal tissue. The comet assay of hepatocytes is well established; however, the levels of systemic drug exposure following systemic administration are often insufficient to evaluate the genotoxic potential …

WebThe comet assay or single-cell gel (SCG) test is a microgel electrophoresis technique that measures DNA damage at the level of single cells. A small number of cells suspended in a thin agarose gel on a microscope slide is lysed, electrophoresed, an. … more. Techniques: Electrophoresis, Comet Assay, Cell Lysis, Image Analysis, Statistical ... WebThe Comet assay is susceptible to subtle artifacts of manipulation depending on the type and timing of sampling performed. Therefore, in the reporting of DNA damage detected by the Comet assay, the context of how the DNA damage was created also needs to be reported and considered in the interpretation of Comet assay results.

Webcould confound results. The comet assay may be combined with an in vivo erythrocyte micronucleus test and/or incor - porated into a repeated dose toxicity test to conserve animal use. Details regarding comet assay testing parameters are readily available1, 3–5 and will not be covered here. Interpretation of comet assay results is conventionally Websimilar to a comet, where DNA fragments (comet tail) migrate through the gel matrix while intact/undamaged DNA remains static (comet head). Commonly generated metrics such as percentage of fragmented DNA in the comet tail and tail moment are a direct measure of cellular DNA damage following treatment. Automated Comet Assay Imaging and
