  • antibody
  • This prospective, multicenter study evaluated the accuracy, safety, and immunogenicity of carcinoembryonic antigen (CEA) antibody imaging in women with known or suspected breast carcinoma. (nih.gov)
  • He is well known for the discovery of a melanoma-related antigen (later, it is called, Chondroitin Sulfate Proteoglycan-4 (CSPG4)) by producing a monoclonal antibody. (wikipedia.org)
  • malignant
  • Malignant endothelial cells also commonly retain the antigen, so that CD31 immunohistochemistry can also be used to demonstrate both angiomas and angiosarcomas. (wikipedia.org)
  • human
  • Carcinoembryonic antigen, as measured by radioimmunoassay, is present in two different human colonic tumors that have been serially transplanted and maintained in the cheek pouches of unconditioned, adult golden hamsters. (sciencemag.org)
  • diagnostic
  • Similarly, the antigen level cannot, by itself, provide enough diagnostic certainty to confirm or rule out suspected cancer. (annals.org)
  • useful
  • Tumor antigens, because of their relative abundance in tumor cells are useful in identifying specific tumor cells. (wikipedia.org)
  • normal
  • This classification, however, is imperfect because many antigens thought to be tumor-specific turned out to be expressed on some normal cells as well. (wikipedia.org)
