CEA is a monomeric glycoprotein (molecular weight approximately 180000 daltons) with a variable carbohydrate component of approximately 45‑60 %. CEA, like AFP, belongs to the group of carcinofetal antigens that are produced during the embryonic and fetal period.

Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth.

2022年4月11日 · What is a CEA test? A carcinoembryonic antigen (CEA) test measures a specific blood glycoprotein called CEA. It means a protein with a lot of sugars added to it by normal or cancerous cells. Scientists first discovered CEA in 1968 when they isolated extracts of liver metastasized by colorectal cancer and also from normal fetal digestive tract.

Carcinoembryonic antigen unit conversion calculator – Convert Carcinoembryonic antigen (CEA) levels ng/mL to µg/L or µg/L to ng/mL. How to use Carcinoembryonic antigen Unit Conversion? You can follow this step: How to convert Carcinoembryonic antigen ng/mL to µg/L?

CEA 属于称为 CEA 相关细胞粘附分子 (CEACaMs) 的免疫球蛋白家族，CEA 与内皮细胞的各种功能密切相关，包括细胞在体内和体外的粘附、增殖和迁移。 它存在于正常细胞细胞膜的腔内侧，被认为可以抑制细胞凋亡，因此参与肿瘤发病机制。 PART03：癌胚抗原（CEA）的临床应用——健康人群筛查. 在健康、不吸烟的成年人中，CEA 在 ≤5.0 µg/L 的水平下被认为在正常范围内，其生理性升高主要见于妊娠期（小肠、肝脏、胰腺细胞都有合成CEA的能力）与吸烟者（吸烟者可 …

The Access carcinoembryonic antigen (CEA) assay is a 2-site immunoenzymatic sandwich assay using 2 mouse monoclonal anti-CEA antibodies (MAb) that react with different epitopes of CEA. A sample is added to a reaction vessel, along with the first anti-CEA MAb-alkaline phosphatase conjugate and the second anti-CEA Mab bound to paramagnetic particles.

This assay is intended for the in vitro quantitative determination of carcinoembryonic antigen in human serum and plasma. 1 The Elecsys CEA assay is further indicated for serial measurement of CEA to aid in the management of cancer patients. The main indication for CEA determinations is the follow-up and therapy-management of colorectal carcinoma.

2025年2月14日 · Serum CEA (carcinoembryonic antigen) is a cell-adhesive glycoprotein that was discovered in colorectal cancer in 1965, and is hence one of the oldest and most used tumor markers. Its name derives from its normal expression …

The Roche CEA electrochemiluminescent immunoassay is used. Results obtained with different test methods or kits cannot be used interchangeably. Measurement of CEA has been shown to be clinically relevant in the management of patients with colorectal, breast, lung, prostatic, pancreatic, and ovarian carcinomas.
