Description

Carcinoembryonic Antigen (101-115) is a synthetic peptide fragment corresponding to a specific epitope region of the Carcinoembryonic Antigen (CEA) protein. This high-purity peptide is a critical reagent for advanced immunological research and diagnostic assay development. It is primarily utilized by biotechnology and pharmaceutical R&D teams, as well as diagnostic manufacturers, for applications in antibody production, epitope mapping, and the calibration of immunoassays targeting CEA.

Application

• Antibody Production & Characterization: Serves as a key immunogen for generating monoclonal and polyclonal antibodies specific to the CEA protein.
• Diagnostic Assay Development: Used as a reference standard or coating antigen in the development and validation of ELISA, chemiluminescence, and other immunoassays for CEA detection.
• Epitope Mapping Studies: Essential for identifying and characterizing antibody-binding sites (epitopes) on the CEA molecule.
• Biomarker Research: Employed in cancer research to study the role of CEA in tumor progression, metastasis, and as a therapeutic target.
• Quality Control Reagent: Acts as a critical positive control in the quality assurance of CEA-targeting diagnostic kits and reagents.
• Competitive Binding Assays: Utilized in competitive inhibition experiments to determine antibody affinity and specificity.
