DNA-hosted Hoechst dyes: application for label-free fluorescent monitoring of endonuclease activity and inhibition†
Abstract
A simple and facile approach was developed for monitoring EcoRI endonuclease activity and inhibition, in which a hairpin-like DNA containing restriction cutting site for EcoRI endonuclease acts as the sensing element and Hoechst dyes as the signal indicator in a label-free format.
