A rapid, convenient and safe in vitro assay system for base excision repair is described. Whole cell exts. are prepd. by detergent-based cell lysis and provide a vigorous activity of AP site repair. A circular DNA substrate is used for detection of both DNA polymerase b-dependent and proliferating cell nuclear antigen (PCNA)-dependent pathways. Repaired and unrepaired DNA substrates are sepd. by agarose gel electrophoresis as a linear DNA mol. and a nicked circular mol., resp., and detected by staining with SYBR Green I. This assay system does not require radioactive substrates or nucleotides, and provides a sensitivity in which 10 ng of a DNA substrate per reaction is sufficient for quant. repair anal.
