Nucleic acid constructs and methods of use
The present invention provides oligonucleotide constructs, sets of such oligonucleotide constructs, and methods of using such oligonucleotide constructs to provide validated sequences or sets of validated sequences corresponding to desired ROIs. Such validated ROIs and constructs containing these have a wide variety of uses, including in synthetic biology, quantitative nucleic acid analysis, polymorphism and/or mutation screening, and the like.
1. A set of nucleic acid constructs, wherein:
a) each nucleic acid construct of the set comprises:
a nucleic acid sequence comprising a region of interest (ROI);
at least one unique identifier oligonucleotide attached to the nucleic acid sequence that distinguishes the nucleic acid construct from other nucleic acid construct(s) in the set having nucleic acid sequence(s) comprising the same ROI;
two or more universal priming sites; and
at least one subset-specific priming site; and
b) the set of nucleic acid constructs comprises two or more subsets, wherein each subset of constructs is identified by one subset-specific priming site.
2. The set of claim 1 , wherein the nucleic acid constructs comprise nucleic acid sequences comprising two or more different ROIs.
3. The set of claim 1 , wherein one or more of the nucleic acid constructs comprise a single subset-specific priming site.
4. The set of claim 1 , wherein one or more of the nucleic acid constructs comprise two or more subset-specific priming sites.
5. The set of claim 1 , wherein one or more of the nucleic acid constructs comprise a single excision site.
6. The set of claim 1 , wherein one or more of the nucleic acid constructs further comprise two or more excision sites.
7. The set of claim 6 , wherein the two or more excision sites flank the nucleic acid sequence comprising the ROI.
8. The set of claim 1 , wherein one or more of the nucleic acid constructs are immobilized on a solid support.
9. The set of claim 1 , wherein the set comprises at least five nucleic acid constructs having nucleic acid sequences comprising the same ROI and with different unique identifier oligonucleotides.
10. The set of claim 1 , wherein one or more of the unique identifier oligonucleotides comprise a degenerate nucleic acid sequence.
11. The set of claim 1 , wherein the unique identifier oligonucleotides are about 10, about 20, about 30 or more bases.
12. The set of claim 1 , wherein the nucleic acid comprising the ROI comprises DNA or RNA.
13. The set of claim 1 , wherein one or more of the nucleic acid constructs are double-stranded or single-stranded.
14. The set of claim 1 , wherein one or more of the nucleic acid constructs comprise at least two unique identifier oligonucleotides.
15. The set of claim 14 , wherein the two unique identifier oligonucleotides are attached to the same end of the nucleic acid comprising the ROI, or to different ends of the nucleic acid comprising the ROI.
16. The set of claim 1 , wherein the ROI comprises a rare sequence variant, a low-frequency mutation, a minor allelic variant, a polymorphism, a mutation, or a haplotype.
