  • Publication number: 20190284607
    Abstract: The present invention relates to technology for preparing oligonucleotides for detecting a target nucleic acid molecule in a sample. Unlike the conventional methods, the present invention provides a first oligonucleotide candidate group designed appropriately for the first selected nucleotide sequence of the target nucleic acid molecule as a standard instead of simultaneously referring to all of the sequences exhibiting the genetic diversity. Then, an optimal oligonucleotide capable of accurately detecting a target nucleic acid molecule exhibiting genetic diversity in a sample is provided by using the first oligonucleotide candidate group.
