CASP

CASP analyzes comet assay images from single-cell gel electrophoresis to quantify DNA strand breaks for genotoxicity assessment and DNA repair kinetics studies.

Key Features:

• Automated image analysis: Identifies and quantifies comet-shaped patterns to determine the extent of DNA strand breaks.
• Image format compatibility: Processes color and grayscale images of fluorescence-stained comets saved in TIF format.
• Negative image conversion: Supports negative conversion for silver-stained images with dark cells on a white background.
• Validation: Produced reproducible results in experiments using human lymphocytes exposed to gamma-rays.
• Platform compatibility: Operates on multiple platforms and has been tested on Windows 95 and Linux.

Scientific Applications:

• Genotoxicity and cytotoxicity assessment: Evaluation of the effects of chemical compounds, radiation, or other stressors on cellular DNA.
• DNA repair kinetics: Monitoring the kinetics of DNA repair processes following exposure to damaging agents.
• Comparative analysis: Conducting comparative analyses across different experimental conditions or treatments.

Methodology:

Automated image analysis that identifies and quantifies comet-shaped patterns formed by damaged cells to determine the extent of DNA strand breaks.
