A method for enrichment of natural antisense mRNA which involves hybridization of cDNA obtained from sense RNA with cDNA obtained from antisense RNA, followed by DNA polymerase treatment of the sense-antisense hybrid DNA molecule. A natural antisense library can be generated by cloning of sense-antisense hybrid DNA molecules in a vector.

Method for enrichment of natural antisense messenger RNA

This invention provides a method of sorting genes comprising: (1) preparing ds cDNA molecules from mRNA molecules (2) digesting the ds cDNA molecules (3) ligating to the digested cDNA molecules a set of dsDNA oligonucleotide adaptors; (4) amplifying the ligated cDNA molecules; and (5) sorting the amplified cDNA molecules into nonoverlapping groups. This invention also provides two additional methods of sorting genes. This invention further provides a method of making sub-libraries of ligation sets.
