Primer set for preparation of NGS library and method and kit for making NGS library using the same
The present disclosure relates to a primer set for preparation of a library used for next generation sequencing (NGS), and a method and a kit for making an NGS library using the same. The method for making the next generation sequencing (NGS) library using the primer set according to the present disclosure is able to simply analyze large amounts of samples as compared to the existing method for making a library, which is effectively usable for analysis of target DNA sequences or for database construction, in large amounts of samples.
1. A primer set for preparation of a next generation sequencing (NGS) library comprising: a first primer consisting of a first adapter sequence, a first index sequence, a first sequencing sequence, and a first target sequence, and a second primer consisting of a second adapter sequence, a second index sequence, a second sequencing sequence, and a second target sequence, wherein the first primer is selected from the group consisting of SEQ ID NO: 27 to SEQ ID NO: 34, and the second primer is selected form the group consisting of SEQ ID NO: 35 to SEQ ID NO: 46.
2. The primer set of claim 1 , wherein the first adapter sequence is P5 (SEQ ID NO: 1), and the second adapter sequence is P7 (SEQ ID NO: 2).
3. The primer set of claim 1 , wherein the first index sequence is selected from the group consisting of SEQ ID NO: 3 to SEQ ID NO: 10, and the second index sequence is selected from the group consisting of SEQ ID NO: 11 to SEQ ID NO: 22.
4. The primer set of claim 1 , wherein the first target sequence and the second target sequence are bound to the hypervariable region 1 (HV1) of human mitochondrial DNA.
5. The primer set of claim 1 , wherein the first target sequence is SEQ ID NO: 25.
6. The primer set of claim 1 , wherein the second target sequence is SEQ ID NO: 26.
7. A combination of primer sets for preparation of a next generation sequencing (NGS) library comprising: the primer set of claim 1 ; a third primer consisting of a first adapter sequence, a first index sequence, a first sequencing sequence, and a third target sequence; and a fourth primer consisting of a second adapter sequence, a second index sequence, a second sequencing sequence, and a fourth target sequence.
8. The primer combination of claim 7 , wherein the third target sequence and the fourth target sequence are bound to the hypervariable region 2 (HV2) of human mitochondrial DNA.
9. The primer combination of claim 7 , wherein the third target sequence is SEQ ID NO: 67.
10. The primer combination of claim 7 , wherein the fourth target sequence is SEQ ID NO: 68.
11. The primer combination of claim 7 , wherein the third primer is selected from the group consisting of SEQ ID NO: 47 to SEQ ID NO: 54, and the fourth primer is selected form the group consisting of SEQ ID NO: 55 to SEQ ID NO: 66.
12. The primer combination of claim 7 , wherein the primer sets further comprise 1 to 22 primer set(s) of which only the target sequence is different from that of the primer set of claim 7 .
13. A method for making a next generation sequencing (NGS) library comprising:
(a) extracting DNA from a sample;
(b) amplifying target DNA using the combination of primer sets of claim 7 ; and
(c) library pooling by purifying the amplified product.
14. The method of claim 13 , wherein the target DNA is HV1 or HV2 of mitochondria.
15. A kit for making a next generation sequencing (NGS) library comprising the combination of primer sets of claim 7 .
