The bacterial rapid approach to DNA adduct recovery (RADAR) assay allows for the rapid lysis and trapping of DNA-topoisomerase cleavage complexes, as well as other proteins covalently attached to DNA. These covalently attached proteins can be quantified when the isolated DNA is immunoblotted. Significantly, the bacterial RADAR assay described here requires no large, expensive lab equipment, thus making it accessible to most laboratories. Furthermore, it does not require any long centrifugation steps, which allows for a relatively large number of samples to be processed in 1 day.

摘要

The bacterial rapid approach to DNA adduct recovery (RADAR) assay allows for the rapid lysis and trapping of DNA-topoisomerase cleavage complexes, as well as other proteins covalently attached to DNA. These covalently attached proteins can be quantified when the isolated DNA is immunoblotted. Significantly, the bacterial RADAR assay described here requires no large, expensive lab equipment, thus making it accessible to most laboratories. Furthermore, it does not require any long centrifugation steps, which allows for a relatively large number of samples to be processed in 1 day.
