摘要：
A new technique for the detection of P-32-postlabelled DNA adducts separated by capillary electrophoresis was developed. By direct transfer from the capillary outlet to a positively charged moving filter paper, eluted radioactive peaks can be quantified using a phosphor imaging detector. With this method it is possible to separate DNA adducts from different carcinogens after P-32-postlabelling of the modified and unmodified nucleotides with high sensitivity approaching 1 adduct per 10(9) nucleotides.
