Isoferritins from tumorous and non-tumorous human liver.
Human ferritins purified from normal liver (LF) and from hepatocellular carcinoma (HF) showed different biochemical and immunological characteristics. Subunit preparations from the isoferritins showed differences in isoelectric focusing patterns, although both HF and LF were found to be composed of H and L subunits with apparently the same molecular weights. It is postulated that heterogeneities between the two isoferritins are not merely due to different proportions of H and L subunits, but also result from the existence of distinct species of the subunits bearing different surface electric charges.
