Abstract

Claims (30)

1. An array of polynucleotide molecules on a surface,

wherein said surface comprises nucleotide binding regions separated by non-nucleotide binding regions arranged on the surface in a predetermined pattern;

wherein the nucleotide binding regions comprise nucleotide capture chemistry and the non-nucleotide binding regions do not have the nucleotide capture chemistry;

wherein more than 50% of the nucleotide binding regions in the array are occupied with a single one of the polynucleotide molecules; and

wherein said surface is not a bead.

2. The array of claim 1 , wherein said nucleotide binding regions are discrete spaced apart regions.

3. The array of claim 2 , wherein said non-nucleotide binding regions are inter-regional areas that separate said discrete spaced apart regions.

4. The array of claim 1 , wherein said nucleotide binding regions are arranged in a grid pattern.

5. The array of claim 1 , wherein said polynucleotide molecules are linear or branched.

6. The array of claim 1 , wherein more than 10 5 different polynucleotide molecules are present on the array.

7. The array of claim 1 , wherein at least part of the sequence of each of said polynucleotide molecules attached on the nucleotide binding regions is not known.

8. The array of claim 7 , wherein each of said polynucleotide molecules comprises a nucleotide sequence of genomic DNA, cDNA, or RNA.

9. The array of claim 1 , wherein said nucleotide capture chemistry is a plurality of oligonucleotides in each nucleotide binding region that binds one of said polynucleotide molecules to each region.

10. The array of claim 9 , wherein

each oligonucleotide in each nucleotide binding region contains a nucleic acid sequence that is complementary to and hybridizes with said polynucleotide molecules.

11. The array of claim 10 , wherein

said nucleic acid sequence of the oligonucleotides in each nucleotide binding region is identical to nucleic acid sequences contained in oligonucleotides in other nucleotide binding regions.

12. The array of claim 9 , wherein said oligonucleotides are 20 to 100 bases in length.

13. The array of claim 9 , wherein said oligonucleotides are produced by nano-printing techniques, or by creating active sites for oligonucleotide attachment using photochemistry.

14. The array of claim 9 , wherein at least part of the sequence of each of said polynucleotide molecules attached on the nucleotide binding regions is not known.

15. The array of claim 14 , wherein said oligonucleotides are directly attached to said surface, and said polynucleotide molecules comprising said unknown sequence are hybridized directly to said oligonucleotides.

16. An array of polynucleotide molecules on a surface,

wherein said surface comprises nucleotide binding regions separated by non-nucleotide binding regions arranged on the surface to form a predetermined pattern;

wherein the nucleotide binding regions comprise nucleotide capture chemistry and the non-nucleotide binding regions do not have the nucleotide capture chemistry;

wherein the nucleotide binding regions in the array are occupied with a single one of the polynucleotide molecules;

wherein said surface is not a bead; and

wherein at least part of the sequence of each of said polynucleotide molecules attached on the nucleotide binding regions is not known.

17. The array of claim 16 , wherein said nucleotide capture chemistry is a plurality of oligonucleotides in each nucleotide binding region that binds one of said polynucleotide molecules to each region.

18. The array of claim 17 , wherein each oligonucleotide in each nucleotide binding region contains a nucleic acid sequence that is complementary to and hybridizes with said polynucleotide molecules.

19. The array of claim 18 , wherein said nucleic acid sequence of the oligonucleotides in each nucleotide binding region is identical with nucleic acid sequences contained in oligonucleotides in other nucleotide binding regions.
