Abstract

The invention relates to methods for pairwise sequencing of a double-stranded polynucleotide template, which methods result in the sequential determination of nucleotide sequences in two distinct and separate regions of the polynucleotide template. Using the methods of the invention it is possible to obtain two linked or paired reads of sequence information from each double-stranded template on a clustered array, rather than just a single sequencing read from one strand of the template.

Claims

1. A method for pairwise sequencing of first and second regions in individual double stranded target polynucleotides of a plurality of double stranded target polynucleotides, wherein each of the double stranded target polynucleotides comprises a first strand and a complementary strand, comprising

(a) providing a solid support,

wherein the first strands of the plurality of double stranded target polynucleotides are linked to the solid support,

wherein a plurality of primers is linked to the solid support, and

wherein the primers are capable of hybridizing to a first region of the first strands;

(b) obtaining sequence data from the first region of the first strands by subjecting the first strand region of the first strands on the solid support to a sequencing method;

(c) hybridizing the primers to the first strands after obtaining the sequence data from the first region of the first strands and then extending the primers to copy the first strands, thereby generating the complementary strands of the double stranded target polynucleotides, whereby the complementary strands are linked to the solid support; and

(d) obtaining sequence data for a second region of the second strands, wherein the sequence data for the first region and the second region provides a pairwise sequence of the first and second regions of individual target polynucleotides in the plurality of double stranded polynucleotides.

2. The method of claim 1, wherein the double stranded target polynucleotides comprise genomic DNA fragments or amplified fragments of genomic DNA.

3. The method of claim 1, wherein the first and second regions occur at the ends of the individual double stranded target polynucleotides.

4. The method of claim 1, wherein the sequence data is obtained by extension of a sequencing primer with labeled nucleotides.

5. The method of claim 4, wherein the sequencing primer is linked to the solid support.

6. The method of claim 1, wherein the sequence data is obtained by extension of a sequencing primer with labeled oligonucleotides.

7. The method of claim 6, wherein the sequencing primer is linked to the solid support.

8. The method of claim 1, wherein a nicking enzyme generates free 3′

hydroxyls on the plurality of primers that is linked to the solid support.

9. The method of claim 8, wherein the nicking enzyme comprises Uracil DNA glycosylase (UDG), DNA glycosylase-lyase Endonuclease VIII, or FPG glycosylase.

10. The method of claim 8, wherein the solid support further comprises amplification primers and the method further comprises blocking 3′

hydroxyl groups of the amplification primers prior to generating a free 3′

hydroxyl on the immobilized primers.

11. The method of claim 10, wherein the blocking comprises addition of dideoxynucleotide triphosphates to the 3′

hydroxyls.

12. The method of claim 1, wherein the 5′

ends of the first strands are linked to the solid support.

13. The method of claim 1, wherein the 5′

ends of the complementary strands are linked to the solid support.

14. The method of claim 1, wherein the solid support comprises a plurality of beads and the plurality of double stranded target polynucleotides are immobilized on the beads.

15. The method of claim 1, wherein the sequence data is obtained by pyrosequencing.

16. The method of claim 1, further comprising removing the plurality of first strands from the solid support after extending the primers to copy the first strands.

17. The method of claim 1, further comprising deblocking the primers that are attached to the solid support to release an extendable 3′

hydroxyl prior to the extending of the primers to copy the first strands.
