Application

Apoferritin from equine spleen has been used:
  • to determine its partition coefficients in phase systems[1]
  • in NaCl for iron loading of cultured cells[2]
  • in in situ liquid scanning transmission electron microscope for imaging the interface of biology and nanotechnology[3]

Biochem/physiol Actions

This protein shell of ferritin lacking iron is widely used for the calibration of gel filtration columns and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis.[4] It is very abundant in beta-cells of the pancreas where it acts as an anti-oxidant.[5] When added to cultured endothelial cells apoferritin is taken up in a dose-responsive manner and appears to protect the cells from oxidant-mediated cytolysis. [6]

Physical form

Solution in 0.135 M sodium chloride.
