Anti-CEA Antibody [CEA-Y2]

Carried as a ready-to-use liquid reagent from Antibodies.com, the mouse monoclonal IgG1 antibody clone CEA-Y2 targets human carcinoembryonic antigen (CEA) and is directly conjugated to horseradish peroxidase (HRP) for direct enzymatic signal generation. CEA is a heavily glycosylated cell-surface glycoprotein broadly studied as a clinical tumor marker in colorectal, pancreatic, breast, and lung cancers, so HRP-labeled detection antibodies against it are valuable tools in oncology research and immunoassay development.

The reagent is offered with verified human reactivity and an IgG1 isotype, properties that make it useful for laboratories screening hybridoma clones, validating antigen-capture reagents, running competitive inhibition studies, or profiling glycoprotein expression in patient-derived samples. Direct HRP conjugation removes the need for a separate secondary antibody incubation, streamlining ELISA plate-based workflows and reducing background noise typically introduced by indirect detection approaches.

Supplied as 200 µl of liquid, the antibody supports routine plate coating, immunodetection on Western blots, and immunohistochemistry protocols where direct enzymatic reporting is preferred. Researchers investigating tumor biomarker kinetics, calibrating quantitative reference standards, or building diagnostic prototypes for gastrointestinal and pancreatic cancer screening will find this clone a flexible addition to their antibody panel.
