Carcinoembryonic antigen-related cell adhesion molecule 5 (694-702)

Carcinoembryonic antigen-related cell adhesion molecule 5 (694-702) is a synthetic peptide fragment derived from the CEA-related cell adhesion molecule 5, a member of the immunoglobulin superfamily involved in intercellular adhesion and signal transduction. This specific peptide sequence corresponds to amino acid residues 694 to 702 of the parent protein, representing a region of interest for researchers investigating molecular recognition, antigenicity, and peptide-protein interactions. Its defined sequence and biochemical properties make it a valuable tool for studying the functional domains of CEACAM5 and their role in cellular processes, including cell adhesion, signaling, and immune recognition.

Epitope mapping: The peptide is highly relevant for epitope mapping studies, enabling researchers to identify and characterize antibody binding sites within the CEACAM5 protein. By using this defined sequence in immunoassays such as ELISA or Western blot, investigators can determine whether specific monoclonal or polyclonal antibodies recognize this region, facilitating the development of targeted immunoreagents and advancing the understanding of antigen-antibody interactions at a molecular level.

Immunogenicity assessment: Researchers utilize the 694-702 peptide to evaluate its immunogenic potential, particularly in the context of generating peptide-specific antibodies in animal models. Such studies are essential for dissecting the immune response to defined protein regions, supporting the creation of novel research antibodies, and assessing the specificity and cross-reactivity of immune reagents directed against CEACAM5 family members.

Peptide-based assay development: The defined sequence of this peptide fragment supports the development of peptide-based assays aimed at detecting or quantifying anti-CEACAM5 antibodies in biological samples. By serving as a standard or capture reagent in immunoassays, the peptide enables sensitive and specific measurement of immune responses, facilitating biomarker discovery, quality control, and the evaluation of humoral immunity in experimental systems.

Protein-protein interaction studies: The 694-702 fragment provides a valuable molecular probe for investigating the interaction interfaces within the CEACAM5 protein or between CEACAM5 and other cellular partners. Through binding studies, surface plasmon resonance, or pull-down assays, researchers can assess the contribution of this region to adhesion processes, signaling cascades, or the modulation of cellular responses, gaining insight into the functional architecture of the protein.

Peptide structure-function analysis: The synthetic nature of this peptide allows for detailed structure-function investigations, including the assessment of sequence modifications, conformational preferences, and the impact of specific residues on biological activity. Researchers can employ spectroscopic methods, molecular modeling, or mutagenesis studies to elucidate the structural determinants underlying the biological roles of the CEACAM5 694-702 region, thereby advancing the broader understanding of cell adhesion molecules in health and disease.
