Effect of cryopreservation on DNA damage and DNA repair activity in human blood samples in the comet assay

open access: yesArchives of Toxicology, 2021
The comet assay is a commonly used method to determine DNA damage and repair activity in many types of samples. In recent years, the use of the comet assay in human biomonitoring became highly attractive due to its various modified versions, which may be

Detection of DNA damage by alkaline comet assay in mouse colonic mucosa

open access: yesSTAR Protocols, 2021
Summary: We recently characterized the association between DNA damage and immunoresponse in vivo in colonic mucosa of mice infected with a Salmonella Typhimurium strain expressing a genotoxin, known as typhoid toxin.

Validation of the 3D reconstructed human skin Comet assay, an animal-free alternative for following-up positive results from standard in vitro genotoxicity assays

open access: yesMutagenesis, 2020
As part of the safety assessment process, all industrial sectors employ genotoxicity test batteries, starting with well-established in vitro assays. However, these batteries have limited predictive capacity for the in vivo situation, which may result in ...

Using a medium-throughput comet assay to evaluate the global DNA methylation status of single cells

open access: yesFrontiers in Genetics, 2014
The comet assay is a simple and cost effective technique, commonly used to analyse and quantify DNA damage in individual cells. The versatility of the comet assay allows introduction of various modifications to the basic technique.

Interpreting sperm DNA damage in a diverse range of mammalian sperm by means of the two-tailed comet assay

open access: yesFrontiers in Genetics, 2014
Sperm DNA damage is associated with fertilization failure, impaired pre-and post- embryo implantation and poor pregnancy outcome. A series of methodologies to assess DNA damage in spermatozoa have been developed but most are unable to differentiate ...

Automated comet assay analysis [PDF]

open access: yesCytometry, 1999
Recently the "comet assay" or "single-cell gel electrophoresis assay" has been established as a sensitive method for the detection of DNA damage and repair. Most of the software now available to quantify various parameters for DNA damage requires the interaction of a human observer. In this report, we describe an automated analysis system that is based

Comet Assay measurements: a perspective [PDF]

open access: yesCell Biology and Toxicology, 2007
The Comet Assay or single cell gel electrophoresis assay is one of the very widely used assays to microscopically detect DNA damage at the level of a single cell. The determination of damage is carried out either through visual scoring of cells (after classification into different categories on the basis of tail length and shape) or by using different ...

MalariaCometChip for high-throughput quantification of DNA damage in Plasmodium falciparum

open access: yesSTAR Protocols, 2021
Summary: Comet assay is a standard approach for studying DNA damage in malaria, but high-throughput options are not available. The CometChip was previously developed using mammalian cells as a high-throughput version of the comet assay.

Potassium bromate as positive assay control for the Fpg-modified comet assay.

open access: yesMutagenesis, 2020
The comet assay is a popular assay in biomonitoring studies. DNA strand breaks (or unspecific DNA lesions) are measured using the standard comet assay.

Is the Comet Assay a Sensitive Procedure for Detecting Genotoxicity?

open access: yesJournal of Nucleic Acids, 2010
Although the Comet assay, a procedure for quantitating DNA damage in mammalian cells, is considered sensitive, it has never been ascertained that its sensitivity is higher than the sensitivity of other genotoxicity assays in mammalian cells. To determine
