Özet

The single cell gel electrophoresis or Comet assay is a visual, sensitive, relatively inexpensive and noninvasive technique for quantitating DNA damage and repair in vivo and in vitro in any eukaryotic cell and some prokaryotic cells. It also has an advantage over the other DNA damage-detecting methods, such as micronucleus assay, sister chromatid exchange and alkali elution, because of its high sensitivity. However, the Comet assay has gained increasing popularity for use in human biomonitoring, genotoxic, and cell biological studies. These studies have shown that the parameters of tail moment and among other comet parameters such as comet length, comet intensity, head length, head intensity, tail length, tail intensity, tail DNA and olive tail moment were generally highly correlated. Among these parameters of Comet features have been developed. Especially, tail parameters that are the most frequently used are those of the tail moment, the tail DNA, and the tail length, moreover these parameters have been used by many researchers for radiation studies, but the tail moment and tail DNA showed more sensitivity than the tail length. Nevertheless, the tail DNA was more accurate than the tail moment in comparing the sensitivity of the alkaline and neutral assays in an experimental cell study, it is of interest to investigate which parameter is more suitable and safer for measuring DNA damages in a human biomonitoring study. The reliability of the results in terms of parameters of the tail moment and the tail DNA studies should be evaluated together.
