摘要:
In a PCR in which template nucleic acid (tNA), at least one primer, deoxynucleotide triphosphates (dNTP) and a polymerase (I) with proofreading activity are used, the new feature is that at least one target substrate (TS) is added. An independent claim is also included for a kit for performing PCR, performed as above, that includes a TS.

PROBLEM TO BE SOLVED: To provide a method for detecting the difference of detected sequences. SOLUTION: The invention relates to the detection of nucleic acid sequence differences using coupled ligase detection reaction (LDR) and polymerase chain reaction (PCR). One aspect of the invention involves use of a ligase detection reaction coupled to a polymerase chain reaction. Another aspect of the invention relates to the use of a ligase detection reaction coupled to a secondary polymerase chain reaction coupled to primary polymerase chain reaction. A third aspect of the invention involves a secondary polymerase chain reaction coupled to a primary polymerase chain reaction. Such coupling of the ligase detection reaction and the polymerase chain reaction permits multiplex detection of nucleic acid sequence differences. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method useful for combining amplification and hybridization probe detection of an amplified target nucleic acid sequence and obtain a reagent for the same. SOLUTION: The method is performed by combining the PCR amplification including a process for bringing the target nucleic acid sequence to contact with the PCR reagent containing at least 2 PCR primers and a polymerase essentially defected in all 5' to 3' exonuclease activity, an oligonucleotide, a fluorescent material molecule attached to the first position of the nucleotide, a light-extinguishing material molecule attached to the second position of the oligonucleotide and an oligonucleotide probecontaining 3' terminal brought to be not affected by 5' to 3' elongation activity of the polymerase, and a process for feeding the target nucleic acid sequence, the oligonucleotide probe and the PCR reagent to a heat circulation sufficient to amplify the target nucleic acid sequence specified with the PCR reagent, with the hybridization probing.
