  • Protein as a diagnostic of cancer
    Patent number: 6187549
    Abstract: The presence of A-protein in an abnormally large amount in a sample, such as blood, from an individual is diagnostic of primary or metastatic cancer in the individual. The presence of A-protein is most readily detected by immunological reaction of it with specific antibodies. A preferred procedure for detecting the presence of A-protein in samples is by a sandwich assay using two antibodies with different epitopic specificities for A-protein.
