A three step purification procedure for human liver ferritin

We describe a method for the purification of normal human liver ferritin by ultrafiltration, gel filtration on Sephacryl S-300, and affinity chromatography on DEAE-Affi Gel Blue. The purity of the ferritin obtained was verified by immunoelectrophoresis, Ouchterlony immuno-diffusion, polyacrylamide gel electrophoresis, and electrofocusing. This rapid method yields 32% of the original ferritin.
