Two Sensitive PCR-Based Methods for Detection of Hepatitis B Virus Variants Associated with Reduced Susceptibility to Lamivudine
1 Oct 1999
Abstract excerpt
Two novel assays, a restriction fragment length polymorphism (RFLP) assay and an assay based on the 5'-nuclease activity of Taq DNA polymerase, were developed for screening viral variants in lamivudine-treated patients' sera containing <1,000 copies of the hepatitis B virus (HBV) genome per ml. Both assays were designed to detect single-nucleotide changes within the HBV DNA polymerase gene that are associated...
