1. A method of isolating a target nucleic acid molecule, the method comprising:
- (a) providing a plurality of nucleic acid molecules;
(b) providing a library of oligonucleotide tags, each oligonucleotide tag comprising a region having a different sequence than the other tags in the library and comprising a primer binding site;
(c) ligating at least a subset of the plurality of nucleic acid molecules with the library of oligonucleotide tags, thereby generating a population of conjugates, wherein each conjugate has a unique oligonucleotide tag that is different in sequence than that of the other conjugates;
(d) amplifying in a pool at least a subset of the population of conjugates using one or more primers each having sequence complementarity to the primer binding site thereon;
(e) isolating at least one conjugate of the amplified conjugates from the pool, wherein the isolated conjugate comprises a target nucleic acid molecule having a predetermined sequence; and
(f) removing the oligonucleotide tag attached thereto to recover the target nucleic acid molecule.

7. A method of isolating a target nucleic acid molecule, the method comprising:
-
(a) providing a population of nucleic acid molecules having different predetermined sequences; (b) providing a plurality of oligonucleotide sequences that are different from one another in sequence and are immobilized on microparticles, each microparticle having a single copy of oligonucleotide sequence immobilized on its surface, wherein each single copy of oligonucleotide sequence is uniquely complementary to a corresponding nucleic acid molecule of the population; (c) hybridizing the population of nucleic acid molecules to the plurality of oligonucleotide sequences, thereby forming a population of hybridized microparticles, each hybridized microparticle having a single nucleic acid molecule attached thereon via hybridization with its corresponding uniquely complementary oligonucleotide sequence; (d) separating the population of hybridized microparticles into samples, each sample comprising a single hybridized microparticle; and (e) isolating at least one hybridized microparticle comprising a target nucleic acid molecule having a predetermined sequence. - View Dependent Claims (8, 9, 10, 11, 12)

19. A method of isolating a target nucleic acid molecule, the method comprising:
-
(a) providing a population of nucleic acid conjugates, each having a distinct predetermined sequence and a oligonucleotide tag that is different in sequence than that of the other conjugates, wherein each predetermined sequence and each oligonucleotide tag are conjugated via ligation; (b) amplifying in a pool at least a subset of the population of nucleic acid conjugates using primers having sequence complementarity to the oligonucleotide tags conjugated thereto; (c) isolating a target nucleic acid molecule having a predetermined sequence from the amplified nucleic acid molecules in the pool; and (d) removing the oligonucleotide tag conjugated thereto to recover the target nucleic acid molecule. - View Dependent Claims (23, 24, 25)
