One M perchloric acid-soluble fraction separated from cyst fluid of a patient (blood group AB) with ovarian clear cell carcinoma in malignant was subjected to Sephacryl S-200 gel filtration and Fraction 1 which was eluted at void volume, reacted with both of the lectins of Vicia unijuga and Arachis hypogaea. This fraction was then separated into 6 fractions (DEAE-Frs. 1-6) in a DEAE-Sephacel column chromatography. DEAE-Frs. 3-6 were sugar-rich glycoprotein fractions which contained galactose and N-acetylglucosamine in remarkably high percentages, respectively. Reactivities against various hemagglutinins of these four fractions suggest that DEAE-Fr. 3 is a Thomsen-Friedenreich (T) glycoprotein fraction with AB activity and weak N antigen precursor activity and DEAE-Fr. 4 is an N antigen precursor glycoprotein fraction with AB activity and weak T activity.
