The 96-Well CometChip^® System is a high-throughput platform to simultaneously treat and measure DNA damage induced by different treatments, or among different cell types on a single slide using the comet assay. The CometChip^® is a consumable consisting of specifically sized micron pores patterned into agarose. 96 separate wells are created by inserting the CometChip^® into a reusable magnetically-sealed cassette suitable for tissue culture incubators. Cells added to each well are captured by gravity into micropores and excess cells are aspirated, leaving an array of non-overlapping cells. Multiple experimental conditions are performed in parallel by the addition of different chemicals to respective wells. Once treatment is complete the CometChip^® is removed from the cassette and processed using standard alkaline comet conditions and imaging systems. Electrophoresis of the CometChip^® is designed to work with Trevigen's CometAssay^® Electrophoresis System and reagents.

Trevigen’s FLARE™ (Fragment Length Analysis using Repair Enzymes) Assay Kits provide the ability to assess the type of DNA damage using DNA Repair enzymes when used in combination with the comet assay. Cells harvested after treatment are immobilized in low melting point agarose on a specially treated microscope slide.  The cells are gently lysed and then incubated with DNA Repair enzyme to assess the type of damage present.  The slides are then immersed in an alkali solution, to unwind and denature the DNA strands, and subjected to electrophoresis and subsequent DNA staining. The type of DNA damage is inferred from the substrate specificity of the DNA Repair enzyme. Trevigen provides a complete standardized system for consistent results which includes Fpg, hOGG1, and Endo III specific FLARE™ Assay Kits containing FLARE™ Slides designed to work with Trevigen’s CometAssay® Electrophoresis System and reagents.
