Abstract:
AFP from fetal serum and serum of patients with primary hepatic cancer were purified by affinity chromatography. Then, the lentil lectin-reactive and nonreactive variants of these purified glycoproteins were prepared by affinity chromatography with immobilized lectin. Glycopeptides and oligosaccharides were prepared from variants by protease treatment and hydrazinolysis, respectively, and subjected to carbohydrate and amino acid analysis. A small difference in the carbohydrate compositions of each variant was observed. Analysis of chemical compositions of AFP variants is useful for the differential diagnosis between benign liver diseases and primary hepatic cancer.
