CEACAM Antibodies

CEACAM (Carcinoembryonic Antigen-related Cell Adhesion Molecule) antibodies target a family of glycoproteins involved in cell adhesion, intracellular signaling, and immune modulation. CEACAMs are expressed on the surface of epithelial cells, immune cells, and certain cancer cells. Members of the CEACAM family, such as CEACAM1, CEACAM5 (CEA), and CEACAM6, are frequently studied for their roles in tumor biology, particularly in cancers of the colon, breast, and lung. CEACAM antibodies are key tools in cancer research and diagnostics due to their specificity in recognizing CEACAM proteins associated with cell adhesion, metastasis, and immune response.

Content of CEACAM Antibodies

CEACAM antibodies are monoclonal or polyclonal antibodies developed to recognize specific CEACAM isoforms. These antibodies are used to detect the presence and levels of CEACAM proteins on cell surfaces, in tissues, or in bodily fluids. CEACAM antibodies are valuable in research applications such as immunohistochemistry (IHC), Western blotting, flow cytometry, and enzyme-linked immunosorbent assays (ELISA) to study tumor progression, immune interactions, and tissue homeostasis.

• CEACAM1: Plays roles in immune regulation and is often studied in the context of immune checkpoint inhibition and immune surveillance in cancer.
• CEACAM5 (CEA): A widely known tumor marker, often elevated in colorectal and other epithelial cancers. It is used as a diagnostic and prognostic marker in clinical settings.
• CEACAM6: Overexpressed in various cancers and involved in cell migration and metastasis.

Application of CEACAM Antibodies

• Cancer Research: CEACAM antibodies are extensively used in cancer studies due to their role in tumor growth and metastasis. Anti-CEACAM5 (CEA) antibodies are commonly employed to detect tumor markers in cancer diagnostics, especially in colorectal cancer, where CEA levels serve as a biomarker for disease progression and therapeutic response. 
• Immunotherapy Development: CEACAM1 plays a pivotal role in immune checkpoint regulation, making anti-CEACAM1 antibodies critical in the development of immunotherapies. These antibodies help study the interaction between CEACAM1 and immune cells, including their inhibitory effects on T-cell activation. 
• Diagnostic Tools: CEACAM antibodies, particularly against CEACAM5 (CEA), are widely used in clinical diagnostics. Elevated CEA levels are routinely measured in blood samples as a tumor marker for monitoring cancer recurrence and assessing treatment efficacy. 
• Cell Adhesion and Immune Modulation Research: Since CEACAMs are involved in cell adhesion and immune response modulation, CEACAM antibodies are instrumental in studying the biological mechanisms underlying cell-cell interactions and immune cell signaling.

These antibodies are crucial for advancing our understanding of cancer biology, immune regulation, and for developing diagnostic assays and targeted therapies in oncology.
