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 of target polynucleotides, wherein each target polynucleotide comprises a first and second strand, the method comprising:

(a) providing a solid support comprising immobilized first strands of the target polynucleotides;

(b) sequencing the first region of the first strands of the target polynucleotides;

(c) copying the first strands of the target polynucleotides thereby generating the second strands of the target polynucleotides; and

(d) sequencing the second region of the second strands of the target polynucleotides, wherein determining the sequence of the first and second regions of the target polynucleotides achieves pairwise sequencing of the first and second regions of the target polynucleotides.

2. The method of claim 1, wherein the first strands are removed prior to step (d).

3. The method of claim 1, wherein the sequencing is carried out using a sequencing primer in solution.

4. The method of claim 1, wherein the target polynucleotides further comprise a tag.

5. The method of claim 4, further comprising sequencing the tag.

6. The method of claim 5, wherein the tag is sequenced after step (b).

7. The method of claim 5, wherein the tag is sequenced after step (e).

8. The method of claim 1, wherein the first and second regions are located at the ends of the target polynucleotides.

9. The method of claim 1, wherein the sequencing comprises extension of a sequencing primer with labeled nucleotides.

10. The method of claim 1, wherein the support is a planar solid support.

11. The method of claim 1, wherein the method is carried out on an apparatus.

12. The method of claim 1, wherein the first strands comprise a cleavage site that allows for controlled cleavage of the first strands.

13. The method of claim 12, wherein step (d) is carried out by cleavage and the cleavage occurs by chemical, enzymatic or photochemical means.

14. The method of claim 12, wherein the cleavage site is an abasic site.

15. The method of claim 14, wherein the abasic site is generated from a uracil or an 8-oxo-guanine.

16. The method of claim 1, wherein the sequencing is carried out by pyrosequencing, massively parallel signature sequencing, or sequencing-by-ligation.

17. The method of claim 1, wherein step (c) is carried out using amplification primers, wherein the amplification primers are immobilized to the solid surface.

18. The method of claim 17, wherein the first strands are hybridized to the immobilized primers on the solid surface prior to copying the first strands of the target polynucleotides.

19. The method of claim 18, wherein the immobilized primers are extended to copy the first strands of the target polynucleotides thereby providing the second strands of the target polynucleotides of step (c).

20. The method of claim 17, wherein the solid support comprises a mixture of at least two amplification primers.
