| Targets |
CEA is a cell surface glycoprotein involved in cell adhesion. It binds to itself and other proteins, mediating homophilic and heterophilic interactions. It is not a drug target but a biomarker. Anti-CEA antibodies target CEA for diagnostic and therapeutic purposes.

|---|---|
| ln Vitro |
CEA is a tumor marker used in the diagnosis of lung cancer. application of CEA as a predictive and prognostic marker. Normally produced during fetal development, CEA is a glycoprotein involved in cell adhesion that stops producing before birth. The specialized sialyfucosylated glycoform of CEA, a glycosylphosphatidylinositol (GPI) cell surface-anchored glycoprotein, functions as an L- and E-selectin ligand for colon cancer and may be essential for the metastasis and spread of colon cancer cells [1].
In vitro, CEA is used as an antigen in immunoassays for the detection of anti-CEA antibodies. It is also used in cell-based assays to study cancer cell adhesion and migration. CEA-expressing cells are used to evaluate the efficacy of anti-CEA therapies. |
| ln Vivo |
In vivo, CEA is used as a target for imaging and therapy. Radiolabeled anti-CEA antibodies are used for PET/SPECT imaging of CEA-expressing tumors. Anti-CEA antibodies and antibody-drug conjugates are being developed for the treatment of CEA-positive cancers.
|
| Enzyme Assay |
CEA levels are measured in serum or plasma using immunoassays (ELISA, chemiluminescence). The assay uses anti-CEA antibodies to capture and detect CEA. The concentration of CEA is determined from a standard curve.
|
| Cell Assay |
CEA-expressing cancer cells (e.g., LS174T, SW620) are cultured. Cell surface CEA expression is confirmed by flow cytometry. The cells are used in binding assays with anti-CEA antibodies or in cytotoxicity assays with anti-CEA antibody-drug conjugates.
|
| Animal Protocol |
Animal models use mice bearing CEA-expressing xenograft tumors. Radiolabeled anti-CEA antibodies are administered for imaging. Anti-CEA therapies (antibodies, ADCs, CAR-T cells) are evaluated by measuring tumor growth and survival.
|
| ADME/Pharmacokinetics |
CEA is a large glycoprotein (MW ~180-200 kDa). It is shed from tumor cells into the bloodstream. Its half-life in circulation is approximately 2-6 days. It is cleared by the liver and kidneys.
|
| Toxicity/Toxicokinetics |
CEA is an endogenous protein. No toxicity is associated with CEA itself. Anti-CEA therapies may have toxicity related to the therapeutic agent (e.g., antibody, ADC).

| Additional Infomation |
A glycoprotein secreted onto the luminal surface of the gastrointestinal epithelium. It is present in feces and pancreatic and biliary secretions and is used to monitor response to colon cancer treatment.
CEA is a tumor marker used in cancer diagnostics. It is not a therapeutic drug. Anti-CEA antibodies and related therapies are in development for cancer treatment. CEA is also known as CD66e. |
