Specific detection of minus-strand hepatitis C virus RNA by reverse-transcription polymerase chain reaction on polyA+-purified RNA

Abstract excerpt

A full-length complementary DNA (cDNA) clone of the hepatitis C virus (HCV) genome was used to prepare full-length plus- and minus-strand RNA. The minus-strand RNA, which contains a polyA(+) tract complementary to the polyU tract found in the plus strand (genomic) RNA, but not the plus strand RNA, was captured with a commercial polyA(+)-tract isolation system. After elution, the minus strand was amplified by...
