BPS plasmid containing 1.3 fold over-length HBV genome (GenBank Accession Number: AF100309.1) has been described previously [7]. Both recombinant human adenovirus serotype 5 harboring precursor of recombinant cccDNA (Adv/prcccDNA) and serotype 8 adeno-associated virus (AAV) have been also described previously [8, 14].
