title: Blood group N antigen precursor glycoproteins and N antigen precursor glycoproteins with Thomsen-Friedenreich (T) activity from human liver metastatic carcinomas.
abstract: 1. Four perchloric acid-soluble fractions (PASFs) from human liver metastases of sigmoid colon carcinoma (LSCC), pancreas carcinoma (LPC), breast carcinoma (LBC) and human normal liver (NL) were subjected to DEAE-cellulose column chromatography and separated into three glycoprotein fractions, respectively. 2. In chromatography, LSCC-PASF and LBC-PASF gave Thomsen-Friedenreich (T)-active glycoprotein, blood group N antigen precursor glycoprotein with T activity and N antigen precursor glycoprotein, respectively. 3. LPC-PASF gave N antigen precursor glycoprotein with T activity and two N antigen precursor glycoproteins. 4. The three glycoprotein fractions from NL-PASF did not exhibit both T activity and N antigen precursor activity.
