  • Publication number: 20140199684
    Abstract: A method of amplifying an HCV nucleic acid in an HCV infected sample comprises amplifying a segment of a DNA template that is complementary to a genome of HCV RNA from the sample by a two-stage PCR, wherein a first stage PCR employs a first outer primer and a second outer primer, and a second stage PCR employs a first inner primer and a second inner primer. The nucleotide sequence of the first outer primer comprises a nucleotide sequence as set forth in SEQ ID NO: 2; or SEQ ID NO:9, wherein optionally 1, 2 or 3 nucleotides are other nucleotides than those of SEQ ID NO: 9. The nucleotide sequence of the second outer primer comprises a nucleotide sequence set forth in SEQ ID NO: 3 or 4; or a nucleotide sequence as set forth in SEQ ID NO: 10 or 11, wherein optionally 1, 2 or 3 nucleotides are other nucleotides than those of SEQ ID NO: 10 and 11.
