  • Human carcinoma antigen
    Patent number: 5808005
    Abstract: A glycoprotein antigen which is generally characteristic of human carcinomas, regardless of the tissue associated with the carcinoma--human carcinoma antigen (HCA)--and which is generally not present on normal human cells. Immunodeterminant-containing fragments of HCA substantially separated from elements of HCA's naturally occurring environment are also disclosed. HCA is generally characterized by: a) a molecular weight in excess of 750,000; b) carbohydrate moieties characteristic of mucin-type glycoproteins and comprising a relatively high proportion of sialic acid, galactose, and N-acetylgalactosamine residues (e.g., at least 50% of the carbohydrate residues are sialic acid, galactose, or N-acetylgalactosamine residues); c) an isoelectric point below pH 3.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: September 15, 1998
    Assignee: Epigen, Inc.
    Inventors: John F. Codington, Svein Haavik
