Here we present a detailed protocol of this method, including a work flowchart, schematic diagram and illustrations on how to calculate “cccDNA copies per (infected) cell”.Keywords: Hepatitis B Virus, Covalently closed circular DNA, cccDNA, T5 exonuclease, Quantitative PCR, Copy number per cellBackgroundThe Hepatitis B virus (HBV), a DNA virus belonging to the family Hepadnaviridae, is a human pathogen persisting in approximately 240 million people globally. It allowed detection of cccDNA in non-human cells (primary macaque and swine hepatocytes, etc.) reconstituted with the HBV receptor, human sodium taurocholate cotransporting polypeptide (NTCP). This method has been used for measuring kinetics of cccDNA accumulation in several in vitro infection models and the effect of antivirals on cccDNA.
