摘要

57 An isolated, purified non-A, non-B hepatitis (NANBH) associated antigen having the properties (a) molecular weight of monomer 77,000 daltons on sodium dodecyl sulphate polyacrylamide gel, (b) monomer reactive with rhesus monkey immune serum, (c) glycoprotein containing about 2% carbohydrate comprising (i) predominantly mannose and (ii) approximately equal molar amounts of fucose and galactose, (d) an aromatic amino acid composition comprising molar ratios of phenylalanine, tyrosine, and trypotophan of about 3:3: 1, respectively, and (e) immunogenicity is disclosed along with methods of preparing and using the antigen.
