Crassostrea gigas ferritin: cDNA sequence analysis for two heavy chain type subunits and protein purification.

Ferritin has been shown as being the principal iron storage in the majority of living organisms. In marine species, ferritin is also involved in high-level accumulation of (210)Po. As part of our work on the investigation of these radionuclides' concentration in natural environment, ferritin was searched at the gene and protein level.
