Abstract

Means for simultaneous parallel sequence analysis of a large number of biological polymer macromolecules. Apparatus and methods may use fluorescent labels in repetitive chemistry to determine terminal monomers on solid phase immobilized polymers. Reagents which specifically recognize terminal monomers are used to label polymers at defined positions on a solid substrate.

Claims

1. A method for determining the incorporation of nucleotides comprising:

(a) providing a nucleic acid array, said array comprising at least two different positionally distinct target template nucleic acids;

(b) contacting said nucleic acid array with at least one nucleotide and a template-dependent nucleic acid polymerase; and

(c) determining the incorporation of the nucleotide directed by one of the template nucleic acids in a primer hybridized to the target template nucleic acid.

2. The method of claim 1, wherein the nucleotide comprises a label and determining the incorporation of the nucleotide comprises detection of the label.

3. The method of claim 2, wherein the label is removable.

4. The method of claim 3, further comprising removing the label following determination of incorporation of the nucleotide.

5. The method of claim 2, wherein the nucleotide further comprises a blocking group that blocks incorporation of additional nucleotides.

6. The method of claim 5, wherein each of the label and the blocking group are removable.

7. The method of claim 6, further comprising removing the label and the blocking group following determination of incorporation of the nucleotide.

8. The method of claim 7, wherein the removal of the label and the blocking group comprises a reaction that removes both the label and the blocking group.

9. The method of claim 7, further comprising repeating steps (b) and (c) following the removal of the label and the blocking group.

10. The method of any one of claims 2-9, wherein the label is a fluorescent label.

11. The method of claim 10, wherein the contacting step comprises contacting the nucleic acid array with a plurality of different nucleotides, each different nucleotide comprising a different fluorescent label allowing the different nucleotides to be distinguished from one another.
