Probe including false-positive-suppressing function, method for designing the same, and method for utilizing the same

A method for detecting or quantitatively determining a target nucleic acid having at least one sequence of any one of SEQ ID NOs:

• 1 to 10 in a test sample with high specificity,
• the method comprising:
• preparing the test sample to detect the target nucleic acid;
• bringing at least one kind of polynucleobase probe in contact with the test sample, the polynucleobase probe comprising:
• in a sequence complementary to a target sequence having at least one sequence of any one of SEQ ID NOs:
• 1 to 10, a sequence in which at least one of bases in a portion complementary to any one sequence of SEQ ID NOs:
• 1 to 10 in the target sequence becomes abasic and/or is substituted;
• and/or a sequence which is cleaved to have, on an end, at least one sequence complementary to a sequence of 2 bases or less in anyone sequence of SEQ ID NOs:
• 1 to 10 in the target sequence;
• and
• detecting or quantitatively determining the target nucleic acid bound to the polynucleobase probe.
