Application

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

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. It is very abundant in beta-cells of the pancreas where it acts as an anti-oxidant. 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.

Physical form

Solution in 0.135 M sodium chloride.

Some of the best nucleating agents in nature are ice-nucleating proteins, which boost ice growth better than any other material. They can induce immersion freezing of supercooled water only a few degrees below 0 °C. An open question is whether this

Ice thickness is arguably one of the most important factors limiting the resolution of protein structures determined by cryo-electron microscopy (cryo-EM). The amorphous atomic structure of the ice that stabilizes and protects biological samples in cryo-EM grids also imprints some

As cryo-EM approaches the physical resolution limits imposed by electron optics and radiation damage, it becomes increasingly urgent to address the issues that impede high-resolution structure determination of biological specimens. One of the persistent problems has been beam-induced movement, which
