title: Homogeneous assays based on deoxyribozyme catalysis.
abstract: We report herein the first homogeneous assays based on the ribonuclease activity of a deoxyribozyme. The previously reported deoxyribozyme was covalently modified with biotin and used to assay biotin-binding interactions through changes in fluorescence upon substrate turnover. Deoxyribozymes with fluorescence-based reporting have the potential to serve as general analytical tools.
