Background:

The comet assay is a standard technique for assessing DNA damage and repair in eukaryotic cells.
Automated software analysis is crucial for efficient and objective evaluation of comet assay data.

Purpose of the Study:

To evaluate the efficacy of CellProfiler, an open-source software, for the automatic analysis of comet assay images.
To compare the performance of CellProfiler with established comet assay analysis software (CASP).

Main Methods:

Digitized images from silver-stained comet assays were analyzed using CellProfiler.
CellProfiler's automated analysis focused on quantifying the percentage of tail DNA.
A comparative analysis was performed between CellProfiler and CASP software.

Main Results:

CellProfiler successfully performed automatic analysis of silver-stained comets.
Results from CellProfiler showed good agreement with the CASP software.
The use of CellProfiler demonstrated significant time savings in comet assay data analysis.

Conclusions:

Open-source software, specifically CellProfiler, is a viable tool for the automatic measurement of comet assay data.
CellProfiler provides a reliable and efficient method for evaluating DNA damage and repair, offering substantial time efficiency.
