title: Enzymatic and chemical cleavage methods.
abstract: Cleavage-based methods of mutation detection offer a simple and intuitive means to detect and in most cases locate mutations within DNA fragment sizes ranging from 500 to 1500 bases. Their main advantages as a presequencing screening technology when scanning for unknown mutations is the potential to increase throughput by multiplexing. Combined with lower reagent costs per sample, mutation scanning methods offer significant advantages over currently available sequencing techniques and are likely to be of increasing importance as genomic sequence data becomes more readily available. Although enzymatic methods offer the advantages of simpler and less hazardous protocols, at present the most robust cleavage methods are based around chemical methods.
