1. Perchloric acid-soluble glycoprotein fraction (PASF) extracted from human liver metastases (LM) of sigmoid colon carcinoma was chromatographed on a DEAE-cellulose column. The main fraction (DEAE-nonadsorbed fraction) passed through the column was then subjected to Sephacryl S-200 superfine gel filtration and separated into 12 fractions. 2. Among 12 fractions, only both Fractions 3 and 4 were demonstrated to be chemically and immunologically homogeneous glycoproteins, respectively, by a combination of chemical composition analysis, SDS-PAGE and EITB assay using antisera against the DEAE-nonadsorbed fractions of PASFs from human LMs, normal liver (NL) and normal sigmoid colon (NSC). Each of Fractions 3 and 4 reacted with anti-LM serum to give one immuno complex on a nitrocellulose sheet in EITB assay, but did not react with anti-NL and -NSC sera. 3. Apparent molecular weights of 80,900 and 62,100, respectively, were found for Fractions 3 and 4. Both the fractions, respectively, had abnormal sugar compositions. Fraction 3 contained sialic acid, fucose, galactose, N-acetylglucosamine and N-acetylgalactosamine, but lacked glucose and mannose, and Fraction 4 contained sialic acid, fucose, galactose and N-acetylglucosamine, but lacked glucose, mannose and N-acetylgalactosamine, as sugar components.
