The mice were injected intravenously with 125I-labelled VLPs, approximately 0.5 µg per animal, and euthanized after 10 min. Liver cells were then isolated by in situ perfusion with collagenase, and separated by low-speed differential centrifugation and subsequent density centrifugation on a Percoll gradient [47]. Radioactivity (counts per minute) was measured in the purified hepatocyte fraction, and in the NPC fraction enriched in LSECs and Kupffer cells.Table 3.
