Abstract

A quantitative and functional DNA ligase assay is disclosed. The assay involves the disruption, using restriction enzymes, of a plasmid containing a reporter gene, followed by a ligation step performed in the presence of the biological sample being assayed for DNA ligase activity. The ligation reaction products are then subjected to a coupled transcription-translation reaction, and the extent of DNA ligation is then quantified.
