WebAnalysis of rat liver isoferritins labelled by NaH14CO3 injection shows that acidic isoferritins decay exponentially, while activity in more basic isoferritins rises over 2–3 days. This suggests that isoferritins of low p I become more basic by post-translational modification, occurring over the whole life time of the protein.
