  • Title: Non-ferritin, non-heme iron pools in rat tissues.
    Author: Mulligan M, Althaus B, Linder MC.
    Journal: Int J Biochem; 1986; 18(9):791-8. PubMed ID: 3758461.
    Abstract:
    Concentrations of intracellular, low molecular weight (LMW) and desferrioxamine B (DF) chelatable Fe, in tissues of normal, Fe-deficient and Fe-loaded female rats, were determined. Ice cold, high speed supernatants were rapidly fractionated on Ultrogel AcA202 or by filter centrifugation. After correction for residual blood and DF effects on Fe proteins, liver, kidney, heart and spleen contained 3-8 micrograms/g LMW Fe, brain 20 micrograms/g, with DF; two-thirds of this was detected without DF. There was little variation with Fe status. MW standardization and fractionation on Sephadex G-25 indicated components of apparent MW 13,000, 1400 and 350; the latter two were rapidly labeled with in vivo 59Fe.
