title: Assay of ribozyme-substrate cleavage by anion-exchange high-performance liquid chromatography.
abstract: An HPLC procedure has been developed that can be used to monitor the rate of phosphodiester cleavage of an oligoribonucleotide substrate by an RNA ribozyme with catalytic activity. The method operates at high substrate concentrations (far beyond K(m)), thus allowing the reactions to approach Vmax of the reaction. This method is an efficient alternative to radioisotope labeling methods.
