Development in ligase-mediated techniques for bio-molecular analysis
连接酶介导的生物分子检测技术

Two oligonucleotide probes are permitted to anneal to the nucleic acid target of interest so that the ends of two probes immediately become adjacent to each other. The ligase can then efficiently join the two juxtaposed oligonucleotide probes by the formation of a phosphodiester bond if and only if perfectly matched base-pairs at the nick are present. During past 20 years, many ligase-mediated techniques have been developed for analyzing various bio-molecules, such as known/unknown point mutations, small-sc...
