  • Method for detecting DNA with probe PNA
    Publication number: 20030165953
    Abstract: An object of the present invention is to provide a method for detecting a target nucleotide sequence using the hybridization method, which has a remarkably improved sensitivity of detection. The method comprises the steps of hybridizing a target nucleotide sequence with a PNA that is complementary to the whole or a part of the target nucleotide sequence and measuring the degree of hybridization at the presence of a denaturing agent.

  • Method for detecting target nucleotide sequence
    Publication number: 20030054378
    Abstract: An object of the present invention is to provide a method for detecting a target nucleotide sequence using a complementary nucleotide sequence that has an excellent sensitivity of detection. The method comprises the steps of converting the target nucleotide sequence to a partially double-stranded nucleotide sequence which is double-stranded at one part and single-stranded in the remaining part and detecting said partially double stranded nucleotide sequence using a nucleotide sequence that is complementary to the target nucleotide sequence.
