Carcinoembryonic antigen for detection of cancer

Serum Levels of Carcinoembryonic Antigen and a Tumor-extracted Carcinoembryonic Antigen-related Antigen in Cancer Patients1

Levels of Carcinoembryonic antigen (CEA) and a tumor-ex tracted CEA-related antigen (TEX) were determined in sera from patients with carcinomas of the breast, colon, lung, head and neck, and a number of miscellaneous categories. The purpose of this study was to compare the levels of each antigen at various stages of malignant disease. Competitive radioimmunoassays developed in our laboratory we...

Radioimmunoelectrophoretic binding assay for the detection of carcinoembryonic antigen.

A new radioimmunoassay (RIA) method has been de scribed. This radioimmunoelectrophoretic binding (REB) technique has been applied to the carcinoembryonic antigen system. In contrast to the RIA method with the use of perchloric acid extraction, in the REB technique the require ment for lengthy and possibly biologically degrading pro cedures on relatively large volumes of sera has been eliminated...

Carcinoembryonic antigen and recurrent colorectal cancer.

Surface plasmon resonance based immunosensor for the detection of the cancer biomarker carcinoembryonic antigen.

An immunoassay in optimised conditions with a highly sensitive surface plasmon resonance (SPR) based biosensor was developed for the detection of the cancer biomarker carcinoembryonic antigen (CEA). Different formats of the immunoassay were initially investigated on the surface of the gold sensor chip. A self-assembled monolayer (SAM) was formed on the gold chip using 11-mercaptoundecanoic acid...
