Non-random distribution of iron entering rat liver ferritin in vivo.
Radioactive iron incorporated into rat liver ferritin in vivo and then released in vitro up to 24h after injection follows 'last-in-first-out' behaviour. Thus, within this period at least, the added iron does not equilibrate with iron already present in the molecule's iron-core.
