Note, the calculated molecular weight of pea ferritin is 28 kDa. Removal of the N-terminal targeting sequence upon protein import into plastids results in a protein with an apparent mol weight of ~23 kDa.This antibody is also recognizing horse ferritin (above 100 ng in Western blot).
Ferritin forms a 24-subunit cage for storing the mineral iron. In plants, ferritin is mainly located in plastid, and its expression is upregulated under iron or oxidation stress.
