From: Heparin at physiological concentration can enhance PEG-free in vitro infection with human hepatitis B virus

Figure 4

Heparin enhancement on HBV infection using the HepG2-NTCP-AS cells were validated by using a HepaRG infection system. (a) A dose-dependent curve of heparin on HBV in vitro infection using human HBV-containing serum and adherent HepaRG cells. Increasing concentrations of heparin treatment (0, 1.5, 4.5, 13.5, 40, 120 μg/ml) were tested in the presence of 1.2% PEG. (b) Heparin can further enhance HBV infection using HepaRG cells in the presence of 1.2% or 4% PEG.
