Cells are embedded in agarose on a microscope slide, lysed, and electrophoresed; the presence of strand breaks allows the DNA to migrate, giving the appearance of a comet tail, the percentage of DNA in the tail reflecting the break frequency. Lesion-specific endonucleases extend the usefulness of the method to investigate different kinds of damage. DNA repair can be studied by treating cells with damaging agent and monitoring the damage remaining at intervals during incubation. An important feature of the assay is that damage is detected at the level of individual cells. By combining the comet assay with fluorescent in situ hybridization (FISH), using labeled probes to particular DNA sequences, we can examine DNA damage and repair at the level of single genes or DNA sequences. Here we provide protocols for the comet assay and the FISH modification, answer some technical questions, and give examples of applications of the technique.","is_dataset_classified":null,"base_score":3.367295829986474,"endowment":3.367295829986474,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21057925","pmcid":null,"openalex_id":"https://openalex.org/W16598834","authors":[],"funders":[],"total_grants":0,"fwci":3.8784,"citation_percentile":0.92869406,"influential_citations":0,"citation_trend":[{"year":2012,"count":2},{"year":2013,"count":3},{"year":2014,"count":3},{"year":2016,"count":5},{"year":2017,"count":2},{"year":2018,"count":3},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2022,"count":1},{"year":2023,"count":1},{"year":2024,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://link.springer.com/content/pdf/10.1007/978-1-60327-409-8_10","host_type":"publisher"},{"url":"https://doi.org/10.1007/978-1-60327-409-8_10","host_type":"book series"},{"url":"https://pubmed.ncbi.nlm.nih.gov/21057925","host_type":"repository"}],"fields_of_study":["DNA Repair Mechanisms","Carcinogens and Genotoxicity Assessment","DNA and Nucleic Acid Chemistry"],"mesh_terms":["Antibodies","Biotin","Cell Fractionation","Cell Line","Digoxigenin","DNA Damage","DNA Repair","Electrophoresis","Humans","Nucleic Acid Denaturation","Sepharose","Solutions","Staining and Labeling","DNA Probes","In Situ Hybridization, Fluorescence","Comet Assay"],"keywords":["Comet assay","DNA damage","DNA","Agarose","Molecular biology","In situ hybridization","In situ","Lysis","DNA repair","Microscope slide","Biology","Fluorescence in situ hybridization","Hybridization probe","Fluorescence microscope","Fluorescence","Chemistry","Chromosome","Gene","Biochemistry","Gene expression","Microscope","Pathology","Physics","Medicine","Optics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life below water"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-13T12:13:46.349050Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
