Methods and apparatus relate to reduction of sequence errors generated during synthesis of nucleic acids on a microarray chip. The error reduction can include synthesis of complementary stands (to template strands), using a short universal primer complementary to the template strands and polymerase. Heteroduplex can be formed be melting and re-annealing complementary stands and template strands. The heteroduplexes containing a mismatch can be recognized and cleaved by a mismatch endonuclease. The mismatch-containing cleaved heteroduplexes can be removed from the microarray chip using a global buffer exchange. The error free synthetic nucleic acids generated therefrom can be used for a variety of applications, including synthesis of biofuels and value-added pharmaceutical products.
摘要:
The invention relates to a process for assembling a polynucleotide from a plurality of oligonucleotides comprising: (a) synthesizing or spotting a plurality of different oligonucleotides on a microarray device or bead device having a solid or porous surface, wherein the plurality of oligonucleotides are attached to the solid or porous surface, and wherein each oligonucleotide comprises a sequence region of from about 10 to about 50 bases that is the same or substantially the same as a sequence region of another oligonucleotide; (b) forming an oligonucleotide complementary to a first oligonucleotide by extending a first primer, wherein said primer is complementary to a portion of said first oligonucleotide; (c) is associating said complementary oligonucleotide from said first oligonucleotide and annealing said complementary oligonucleotide to another oligonucleotide comprising a sequence region that is the same or substantially the same as a sequence region of said first oligonucleotide; (d) repeating the primer extension cycles of step (c) to produce a full-length complementary polynucleotide; and (e) amplifying the assembled full length complementary polynucleotide to produce a full length polynucleotide in desired quantities.

摘要:
Methods and apparatus of some aspects of the invention relate to the synthesis of high fidelity polynucleotides. In particular, aspects of the invention relate to concurrent enzymatic removal of amplification sequences and ligation of processed oligonucleotides into nucleic acid assemblies. According to some embodiments, the invention provides a method for producing a target nucleic acid having a predefined sequence. In some embodiments, the method comprises the step of providing a plurality of oligonucleotides, wherein each oligonucleotides comprises (i) an internal sequence identical to a different portion of a sequence of a target nucleic acid, (ii) a 5′ sequence flanking the 5′ end of the internal sequence and a 3′ flanking sequence flanking the 3′ end of the internal sequence, each of the flanking sequence comprising a primer recognition site for a primer pair and a restriction enzyme recognition site.
