  • Diagnosis of cancer using tumor-mimetic cell surface antigen from chemically modified normal cells
    Patent number: 5705351
    Abstract: A tumor-mimetic cell surface antigen (TMCSA) is produced by chemical treatment of normal human cells with a nucleophilic reagent which causes a hydrophobic-hydrophilic interconversion at the cell surface, such as a halobenzene derivative or a benzene sulfonate derivative. This TMCSA cross-reacts with tumor antigens from every type of tumor examined of any histopathologic type. Cancer is detected by detecting the presence of lymphocytes sensitized to tumor antigens based on their reactivity with TMCSA in a binding assay or lymphocyte stimulation or migration inhibition assay.
    Type: Grant
    Filed: February 26, 1997
    Date of Patent: January 6, 1998

  • Diagnosis of cancer using tumor-mimetic cell surface antigen from chemically modified normal cells
    Patent number: 5635361
    Abstract: A tumor-mimetic cell surface antigen (TMCSA) is produced by chemical treatment of normal human cells with fluordinitrobenzene. This TMCSA cross-reacts with tumor antigens from every type of tumor examined of any histopathologic type. Cancer is detected by detecting the presence of lymphocytes sensitized to tumor antigens based on their reactivity with TMCSA in a binding assay or lymphocyte stimulation assay.
