  • Method of detecting colon cancer
    Patent number: 7252955
    Abstract: An immunological assay and kit for colon cancer screening is disclosed. Fecal glycoproteins are extracted from individual samples such that immunogenicity is maintained. The purified fecal glycoproteins are reacted with antibodies to Colon and Ovarian Tumor Antigen (COTA). The mucin antigen COTA is specifically present in colorectal cancer tissue and not in normal colons. The amount of COTA in the fecal sample is determined and used to indicate the presence of colon cancer.
    Type: Grant
    Filed: November 25, 2003
    Date of Patent: August 7, 2007
    Assignee: Loma Linda University Adventist Health Sciences Center
    Inventors: Keshab D. Pant, John D. McCracken, Omar Fagoaga, Wayne Kelln, Sandra Nehlsen-Cannarella

  • Common antigen for colorectal and mucinous ovarian tumors and process for isolating the same
    Patent number: 4962187
    Abstract: A purified common antigen for colorectal and mucinous ovarian cancer (COTA) is provided which is antigenically distinct from CSAp, CEA and Ca 19-9. The COTA antigen is useful for producing a COTA antibody which is nonreactive with CSAp, CEA or Ca 19-9.
