Definitions
- the present invention relates to a composition for selective amplification of multiple target DNA and an amplification method using the same. Specifically, a composition for suppression PCR for effectively amplifying multiple desired targets in a complex DNA sample such as a genome and a composition using the same. It's about method.
- nucleic acids When nucleic acids are extracted from biological samples such as blood to analyze nucleic acids (DNA or RNA) in living organisms, the amount extracted is generally too small to be directly used for various analyses. Therefore, in order to accurately analyze the extracted nucleic acids, amplification of the extracted nucleic acids is required. need.
- PCR Polymerase Chain Reaction
- a representative method of amplifying DNA is a highly efficient amplification technology that selectively amplifies target genes in large quantities, so it is widely used in various fields. It is widely used in.
- detecting gene mutations related to human cancer development requires high sensitivity and specificity. Since the mutation to be detected belongs to a somatic mutation, it exists in very small amounts mixed with wild-type normal DNA, and is a point mutation or base sequence mutation that does not have a large base sequence difference from the normal gene. This is because false-positives may occur if the target mutation is not accurately recognized in complex insertion/deletion mutations, gene fusion mutations, etc.
- the important requirements for a tumor-specific mutation detection test are (1) sensitivity to detect mutant DNA that exists at a low rate in normal DNA and (2) incorrectly determining normal DNA as mutant DNA.
- the goal is to have specificity that can reduce the false-positive rate as much as possible.
- a variety of testing methods to detect tumor-specific mutations have been developed and used, and representative methods include direct sequencing, allele-specific amplification (AS-PCR), and restriction enzyme fragment length polymorphism. (Restriction Fragment Length Polymorphism; RFLP), TaqMan probe method, ARMS (amplification refractory mutation system) PCR, etc.
- AS-PCR allele-specific amplification
- RFLP restriction enzyme fragment length polymorphism
- RFLP Restriction Fragment Length Polymorphism
- TaqMan probe method amplification refractory mutation system
- ARMS amplification refractory mutation system
- the ARMS-PCR method was developed as a way to improve specificity, which is a drawback of AS-PCR. Like AS-PCR, it is based on the principle that PCR is performed only when the primer consists of a perfectly complementary sequence to the template sequence. (Newton, C. R., et al., 1989. Nucl Acids Res, 17; 2503-2516), has the disadvantage of having to go through experimental trial and error to determine the optimal primer with excellent specificity (Drenkard, E., et al ., 2000. Plant Physiol. 124: 1483-1492).
- the present inventors have made diligent efforts to develop a method that can dramatically increase the specificity of target nucleic acid amplification that exists at a very low concentration, and as a result, an adapter of a specific structure and multiple target DNA sequences to be amplified are used. It was confirmed that multiple target DNA sequences can be effectively, selectively and specifically amplified when specific primers are included and, in particular, the total amount of primers specific to the adapter is set to a specific range, and the present invention was completed.
- One object of the present invention is to provide a top oligo and a bottom oligo containing a molecular marker region containing 2 or more N, a sequence region capable of complementary binding to the bottom oligo, and a strand identifier.
- Adapter containing; PCR primers consisting of sequences specific to part of the adapter sequence; Primers for nested PCR consisting of sequences specific to part of the adapter sequence; and a primer that binds complementary to the target DNA sequence.

- the first PCR reaction was performed by adding 0.4 ⁇ l of 10mM dNTP and 2 units of h-Taq DNA polymerase to the template DNA in a thermocycler under the following reaction conditions: once at 95°C; 95°C for 10 seconds, 57°C for 30 seconds, 68°C for 40 seconds 32 times; 68°C for 10 minutes once.
- Nested PCR used 2ul of DNA amplified in the first PCR as a template and the conditions were the same as the first PCR except for the primers, which were performed by adding primers for nested PCR according to the given conditions.
- a sequencing library suitable for the Illumine Sequencing platform was created using the nested PCR amplification product, and high-throughput sequencing was performed. carried out.
- the sequencing library was electrophoresed on a 2% agarose gel and is shown in Figure 2.
- the ratio of sequences with an intact adapter sequence structure was found to be related to the total amount of primers in the primer pool used to amplify the target DNA sequence.
- the base sequences were determined through NGS using the DNA library selectively amplified in Example 2, and then bioinformatic base sequence analysis was performed. At this time, NGS was performed by taking the same volume of DNA solution from each library. NGS sequence production according to the total amount of primers used for each primer pool is shown graphically in Figure 3. It can be seen that there is a difference in NGS sequence production depending on the total amount of primers used.
- the ratio of sequences with an intact adapter sequence structure was independent of the target DNA sequence and the primer pool used to amplify the target DNA sequence. It was found to be related to the total amount of primers.
- the inclusion rate of more than 80% of a good adapter sequence structure was found in the range of 25 to 400 pmole in the R100 group with the smallest number of targets, but this range was reduced to the range of 100 to 300 pmole in the R600 group with the largest number of targets.
- sequences with intact molecular markers and strand discriminators only the sequences from which these sequences were removed were divided into those in which two or more identical sequence structures were found and those in which only one was found, and then the sequences with two or more identical sequence structures were used to refer to hg38.
- the genome was mapped using the BLAST program. At this time, the proportion of base sequences mapped to the genome is shown graphically in Figure 5. As can be seen in Figure 5, it was confirmed that the size of this ratio varies greatly depending on the total amount of primers included in the reaction, similar to what was confirmed in Figures 3 and 4 described above.
- the amount of base sequences mapped to the target and non-target regions is shown in Figure 6, and a line graph for the target hit rate is also shown. As can be seen in Figure 6, it can be seen that there is a range of the total amount of primers that can produce good mapping quantity and target hit rate depending on each primer pool.
- Reads mapped to the target region for each library were classified by molecular markers and strand identifiers to construct a molecular duplex consensus sequence.
- each strand must consist of at least two or more reads, and the duplex consensus satisfies the standard that both sequences composed of the two strands exist.
- the ratio of base sequences used to construct the molecular double consensus among base sequences with intact adapters was calculated and shown graphically in Figure 8. As this ratio can also be seen in Figure 8, it was confirmed that the range of good results for each primer pool was limited depending on the total amount of primers.
- the conditions for capturing at least 80% of targets of 5 or more duplex sequences were the total amount of primers in the range of 25 to 300 pmole for the R100 group, and the range was reduced to 100 to 200 pmole for R600 with 600 target sites. I was able to confirm.
- the conditions for using primers suitable for selective amplification of multiple targets are that the total amount of primers is in the range of 25 to 300 pmole and the amount of individual primers is in the range of 0.167 to 1.0 pmole under the condition of 20ul of PCR reaction solution. there is.
- duplex consensus sequencing was performed on 1,244 targets in the primer range of 150 to 300 pmole. As can be seen in Figure 12, more than 90% By achieving a good target capture rate, it was confirmed that the quantitative conditions of the primers suitable for selective amplification of multiple targets worked well even for expanded targets.
