Protocol Document
SYNOPSIS:
Motivation
• DNA damage is associated with an increased risk of cancer, aging and disease
• Few methods are available for high throughput analysis of DNA damage
• This protocol is based upon the traditional comet assay wherein DNA migrates more
readily through a matrix when damaged
• 96 samples can be processed in parallel
• Throughput and sensitivity are increased compared to the traditional assay
