Title: Isolation and characterization of blood group N antigen precursor glycoproteins with Thomsen-Friedenreich (T) activity, N antigen precursor glycoproteins and T-active glycoproteins from cyst fluids of malignant ovarian clear cell carcinoma. Author: Yanagi K, Ohyama K, Yamakawa T, Ohkuma S. Journal: Int J Biochem; 1990; 22(9):1015-28. PubMed ID: 2282960. Abstract: 1. Two perchloric acid-soluble glycoprotein fractions from cyst fluids of 2 patients with ovarian clear cell carcinoma in malignant were subjected to a systematic affinity chromatography using Vicia unijuga lectin-Cellulofine column and Arachis hypogaea lectin-Cellulofine column and separated into four glycoproteins, blood group N antigen precursor glycoprotein with Thomsen-Friedenreich (T) activity, N antigen precursor glycoprotein, T-active glycoprotein and serologically inactive glycoprotein, respectively. 2. These serologically active glycoproteins isolated in yields of 0.3-3.3% of PASFs, were proved to be mucin-type glycoproteins with Mw of 509,000-2,772,000 Da and contained 33.9-81.7% carbohydrates.[Abstract] [Full Text] [Related] [New Search]
