  • Publication number: 20200277673
    Abstract: A nucleic acid probe and a nucleic acid sequencing method for performing sequencing while ligating nucleic acids. The nucleic acid probe is a DNA sequencing probe, comprising a first moiety, a second moiety, a linker, and a detectable label. A base of the first moiety is A, T, U, C, or G, a base of the second moiety is a random base and/or a universal base, and 3 bases or more are present in the second moiety. The first moiety and the second moiety are ligated via the linker, the connection between the first moiety and the ligation can be cleaved, and the detectable label is ligated to the second moiety or the linker. The above probe, a combination formed therewith, or a sequencing method using the same can reduce the number or types of probes in nucleic acid sequencing, thereby reducing cost.
