  • Methods and compositions for cancer detection
    Patent number: 4489167
    Abstract: Carcinoembryonic antigen contains immune determinates in common with .alpha.-acid glycoprotein. Carcinoembryonic antigen-containing compositions are purified by adsorption onto antibody to .alpha.-acid glycoprotein. The purified compositions may be employed as standards in carcinoembryonic antigen assays or in the labelled form as tracers. Intact carcinoembryonic antigen is assayed by a modified sandwich-type immunoassay. Other cancer-associated substances may be identified by searching for high molecular weight analogues of normal proteins.
