Abstract

The present invention provides massively parallel oligonucleotide synthesis and purification for applications that utilize large collections of defined high-fidelity oligonucleotides (e.g., from about 10¹ to about 10⁵ different sequences, generally between 25-160 bases in length).

Claims

1-38. -38. (canceled)

39. A method of synthesizing one or more oligonucleotides on a solid substrate, wherein the method comprises:

attaching to a solid substrate one or more ribonucleotides having the following structure;

40. The method according to claim 39, which further comprises transesterifying the one or more oligonucleotides synthesized on the solid substrate, thereby releasing the one or more oligonucleotides form the solid substrate.

41. The method according to claim 39, wherein the one or more oligonucleotides comprises sequences complimentary to an individual genomic library.

42. The method according to claim 41, wherein the one or more oligonucleotides are synthesized by a combinatorial synthesis strategy.

43. The method according to claim 41, wherein the individual is selected from the group consisting of:

mammals, plants, and bacteria.

44. The method according to claim 43, wherein the individual is human.

45. The method according to claim 41, wherein the one or more oligonucleotides are between 80 and 160 nucleotides in length.

46. The method according to claim 44, wherein sequences of the one or more oligonucleotides are complimentary to mRNA sequences in the genomic library.

47. The method according to claim 39, wherein synthesizing the one or more oligonucleotide by sequential addition of one or more additional nucleotides is accomplished by photolithography.

48. The method according to claim 39, wherein the substrate is glass.

49. The method according to claim 40, which further comprises attaching biotin to the one or more oligonucleotides.

50. The method according to claim 49, wherein attaching biotin to the one or more oligonucleotides occurs after transesterification.
