IPC: G01N33/574
Filed: 1994-02-01
Abstract: PURPOSE:To detect an earlier cancer at high sensitivity by measuring a cancer- specific antibody for a human strain-shaped cancer cell existing in the blood of a patient with cancer. CONSTITUTION:A living human strain-shaped cancer cell and an antibody in a patient specimen are reacted in-vitro, an antibody against the human strain- shaped cancer cell in the patient specimen bonded with the human strain-shaped cancer cell is detected by means of a marked secondary antibody to specifically react with it or by means of a marked immune-globulin affinity substance. An amount of the marked antibody is radiation-active in a radio immune-assay and enzyme-active in an enzyme immune-assay, and is detected by light emitting intensity in a light emitting immune assay; therefore, the objective result is obtained. Since the antibody in the patient specimen is amplified, even an earlier cancer can be detected. It is particularly significant that a patient with pancreatic cancer which was difficult to be diagnosed can be clearly discriminated from a normal person. By selecting type of the human strain-shaped cancer cell, the specificity of organ is increased, and the possibility of estimating the primary site of a cancer can be expected.
