How to interpret comet assay results

Web11 mei 2024 · When a comet assay, an increasingly popular in vivo genotoxicity test, shows a positive test result, interpretation of that response requires ruling out any confounding tissue site toxicity. Since the comet assay typically uses only two or three daily doses of test agent, precursor tissue changes indicative of toxicity may be easily overlooked. WebTwo types of test systems exist to meet these information requirements, in vivo genotoxicity assays, which take into account the ... which presents challenges in the interpretation as well as in attempting to model the results in silico.
