Abstract excerpt
CONTEXT: Padlock probes are highly specific reagents for DNA diagnostics that can discriminate gene sequences with single base mutations. When the 3' and 5' terminal regions of the oligonucleotide probes are juxtaposed on a target DNA sequence, they can be circularized by enzymatic ligation and become topologically locked to the target. However, to be useful in solution-based diagnostics, the sensitivity of...
