Abstract

Ion-pair reverse-phase high-performance liquid chromatography is presented as a versatile platform for the rapid analysis of nucleic acid modification reactions in a high-throughput manner. This system allows both sensitive and nonradioactive assays to be developed for a variety of nucleic acid modification reactions. Examples presented here include assays for telomerase, uracil DNA glycosylase, polynucleotide kinase, T4 DNA ligase, C5-DNA methyltransferases, and the mismatch endonuclease CEL I. However, this approach is not confined to these reactions. Indeed the ability to perform a variety of nonradioactive assays with throughput times of 10 min per sample in conjunction with automated data analysis software represents a significant improvement in analytical and preparative nucleic acid enzymology.
