Patent ID: 8859239

Claim:
A method of preparing a target nucleic acid for sequencing comprising the steps of: a) ligating a 3′ adaptor to the target nucleic acid, wherein the 3′ adaptor consists of the nucleotide sequence of SEQ ID NO:66 or is an extended 3′ adaptor comprising the nucleotide sequence of SEQ ID NO:66 with one or more nucleotides added to the 5′ end; b) ligating a 5′ adaptor to the 3′ adaptor-target nucleic acid complex of step (a), wherein the 5′ adaptor consists of the nucleotide sequence of SEQ ID NO:1 or is an extended 5′ adaptor comprising the nucleotide sequence of SEQ ID NO:1 with one or more nucleotides added to the 3′ end; c) reverse transcribing the 3′ adaptor-target nucleic acid-5′ adaptor ligation product of step (b); d) PCR amplifying the reverse transcribed ligation product of step (c); and e) gel purifying the amplified target nucleic acid; provided that at least one of steps (a) and (b) must utilize an extended 3′ or 5′ adaptor, respectively.
