title: The subunit structure of horse spleen apoferritin; the molecular weight of the oligomer and its stability to dissociation by dilution.
abstract: The oligomer molecular weight of horse spleen apoferritin was determined by sedimentation-equilibrium techniques and a value of 443000 found. It is concluded that the apoferritin molecule consists of 24 subunits. At concentrations as low as 0.01mum there is no evidence of subunit dissociation.
