Abstract:
A novel fluorescence detection system was developed for DNA methyltransferase (MTase) activity assay based on a target-protected dumbbell molecular probe mediated cascade rolling circle amplification. It showed excellent specificity and sensitivity with a detection limit of 0.0024 U mL(-1), and potential application in quantitatively monitoring MTase activity and screening of anticancer drugs.
