This preparation of Recombinant Apoferritin is the multi-subunit form of Ferritin, composed of heavy and light chains. It does not contain any iron atoms and is, therefore referred to as Apoferritin, rather than Ferritin. It is produced in E. coli and is provided as a liquid in 10 mM Tris, 150 mM Sodium Chloride, 0.02% Sodium Azide, pH 8.0. Protein content is determined by immunoassay on a Centaur CP analyzer and by the Lowry Protein Assay (BSA standard).
