A continuous kinetic assay for RNA-cleaving deoxyribozymes, exploiting ethidium bromide as an extrinsic fluorescent probe

We describe a rapid and inexpensive method to monitor the kinetics of small RNA-cleaving deoxyribozymes, based on the exogenous fluorophore ethidium bromide. Ethidium binds preferentially to double-stranded nucleic acids, and its fluorescence emission increases dramatically upon intercalation. Thus,...
