Abstract

Human lactoferrins isolated from neutrophilic leucocytes and milk by CM-Sephadex chromatography were similar in Mr (76000) and pI (8.7). Upon acidification, both proteins released their two Fe3+ ions/molecule in a similar biphasic way. Both proteins intravenously injected into mice were cleared from plasma at the same rate. The maximal uptakes by the liver, which occurred 5 min after injection, were inhibited to the same extent by milk lactoferrin used as a competitor.
