Project description:Cell: HBV-infected PHH cells. Methods: PHH cells were infected with 2000 genome equivalents/cell of HBV particles in the presence of 4% PEG8000. Seven days after HBV infection, ChIP-Seq analysis of cccDNA in HBV-infected PHHs was carried out. HBV-infected PHH cells were digested with micrococcal nuclease and resulting mononucleosomes purified by sucrose gradient centrifugation. Nucleosomes were enriched with anti-H3K79succ antibodies by ChIP assay and the associated DNA contained both human and HBV DNA fragments was analyzed by deep sequencing. The HBV-specific reads in ChIP-Seq pilot experiments was quantified and normalized by the reads mapped to the human genome.
