摘要：

When ferritin solutions containing 8-12 Fe-57 atoms/molecule are mixed after iron loading, with ferritin containing a small Fe-56 core (Fe-56-ferritins) or with an equal volume of NaCl solution (controls) and the mixtures are frozen in liquid nitrogen (LN) at specified times, the spectra of the Fe-56-ferritins show that almost all Fe-57 is attached to large clusters, whereas in the controls all Fe-57 is present as isolated atoms, Fe-57 dimers or small clusters and no large Fe-57 containing clusters are observed. This allows that Fe-57 present as solitary or dimer species in ferritin migrates to ferritin molecules containing larger Fe-56 clusters.
