Thank you for visiting nature. Radiotherapy and Oncology. Please help improve this article by adding citations to reliable sources. The damage usually detected are single strand breaks and double strand breaks.

To break down these tightly bound protamine proteins in order to use the comet for sperm, additional steps in the de-condensation protocol are required. It is versatile, relatively simple to perform and sensitive.

Fluorescence in situ hybridization with comets. This section does not cite any sources. The lysis solution often used in the comet assay consists of a highly concentrated aqueous salt often, common table salt can be used and a detergent such as Triton X or sarcosinate.

Recommendations for conducting the in vivo alkaline Comet assay. This sensitivity needs to be handled carefully as it is also vulnerable to physical changes which can affect the reproducibility of results. From Wikipedia, the free encyclopedia. Due to its simple and inexpensive setup, it can be used in conditions where more complex assays are not available.

Environmental and Molecular Mutagenesis. Again this solution can have its pH adjusted depending upon the type of damage that is being investigated. Please help improve this section by adding citations to reliable sources.

However this is not true, both single- and double strand breaks are also detected in neutral conditions. The agarose forms a matrix of carbohydrate fibres that encapsulate the cells, anchoring them in place. Current Protocols in Toxicology.

Acknowledgements We thank R. When damaged, this organization is disrupted. The agarose is considered to be osmotic -neutral, therefore solutions can penetrate the gel and affect the cells without cells shifting position. The detergent dissolves the cellular membranes.

The likely basis for this is that loops containing a break lose their supercoiling and become free to extend toward the anode. Category Commons WikiProject.
