Ratiometric Electrochemiluminescence Sensing of Carcinoembryonic Antigen Based on Luminol.

Analytical Chemistry, 2022
Ratiometric electrochemiluminescence (ECL) sensors can efficiently remove environmental interference to attain precise detection. Nonetheless, two eligible luminophores or coreactants were usually needed, increasing the complexity and restricting their ...

A carcinoembryonic antigen-specific cell therapy selectively targets tumor cells with HLA loss of heterozygosity in vitro and in vivo

Science Translational Medicine, 2022
The CEACAM5 gene product [carcinoembryonic antigen (CEA)] is an attractive target for colorectal cancer because of its high expression in virtually all colorectal tumors and limited expression in most healthy adult tissues.

Carcinoembryonic Antigen

Annals of Internal Medicine, 1986
The level of carcinoembryonic antigen (CEA) is often elevated in the serum of patients with cancer. This article reviews the clinical usefulness of this observation. Carcinoembryonic antigen is not useful for detecting asymptomatic cancer; its sensitivity and specificity are not high, particularly for early stages of disease, so in populations with low

Ultrasensitive and Selective Determination of Carcinoembryonic Antigen Using Multifunctional Ultrathin Amino-Functionalized Ti3C2-MXene Nanosheets.

Analytical Chemistry, 2020
Herein, we report on a two-dimensional amino-functionalized Ti3C2-MXene (N-Ti3C2-MXene)-based surface plasmon resonance (SPR) biosensor for detecting carcinoembryonic antigen (CEA) utilizing a sandwich format signal amplification strategy.

Carcinoembryonic antigen in osteosarcoma

Journal of Surgical Oncology, 1977
AbstractPlasma carcinoembryonic antigen (CEA) assay was done in 30 patients with osteosarcoma. CEA was found positive (> 2.5 ng/ml) in 17 of 21 patients who had active evidence of disease and negative (< 2.5 ng/ml) in all 9 patients who were in complete remission resulting from previous amputation or chemotherapy.

Studies on Carcinoembryonic Antigen

International Archives of Allergy and Immunology, 1972
The presence of carcinoembryonic antigen (CEA) in saline extracts (SE) prepared from adenocarcinomas of the colon has been confirmed. This antigen was also detected in perchloric acid extracts (PAE) and in boiled and ethanol precipitated extracts (BE) of colonic tumors. CEA was present in BE preparations of feces from 4 of 8 patients with colon cancer.
