Abstract
A new glycoprotein is characterized by a protein consisting essentially of 75.+-.6% of .alpha.-amino-acids, a carbohydrate portion of 24.6.+-.5.2%, which contains 8.9.+-.2% of hexoses, 7.1.+-.1.5 of N-acetylated hexosamine, 0.2.+-.0.2% of fucose, 8.4.+-.1.5% of, N-acetylated neuraminic acid; a sedimentation coefficient S.sub.20w of 2.5.+-.0.3 S; a molecular weight of 35,000.+-.5,000, determined in the ultracentrifuge, and a molecular weight of 65,000.+-.10,000, determined in polyacrylamide gel containing sodium dodecyl sulfate; an iso-electric point at pH 3.4.+-.0.4; an extinction coefficient E.sub.1.sup.1%.sub.cm (280 nm) of 1.9.+-.0.3; an electrophoretic mobility in the range between that of .alpha..sub.1 and .alpha..sub.2 -globulins; and a specific immunologic reaction with an antibody specifically directed against the glycoprotein.
