[Study on identification of liver isoferritin by isoelectrofocusing in thin-layer polyacrylamide gels].
Thin-layer IEF, an analytical technique of high resolution for protein, was used to identify the liver isoferritin in Wistar rat, normal human and patients with hepatocellular carcinoma (HCC) respectively. The focusing conditions were 2000 V, 25W, 10 degrees C, 2h. The results showed that the IEF bands of the liver isoferritin in Wistar rat, normal human and patients with HCC were 7, 6, 3 and the pI of the liver isoferritin were 5.76-4.75, 5.80-4.85, 4.50-4.43 respectively. The method and data in this paper might be good reference for in-depth study of the structure and function of ferritin and its applications in clinical medicine.
