Antigen NY-CO-13 (103-111)

Antigen NY-CO-13 (103-111) is a synthetic peptide fragment derived from the NY-CO-13 protein, a tumor-associated antigen recognized for its selective expression in certain malignancies. As a defined sequence within the broader NY-CO-13 antigen, this peptide represents a highly specific epitope that is valuable for immunological research and antigenicity studies. Its unique amino acid composition and precise length make it an important tool for dissecting immune responses, mapping T-cell epitopes, and evaluating antigen presentation mechanisms. The relevance of this peptide extends to fields such as cancer immunology, peptide vaccine research, and the development of immunoassays, where understanding antigen-specific interactions is essential for advancing both basic and applied bioscience.

Epitope Mapping: The NY-CO-13 (103-111) peptide is widely employed in epitope mapping experiments designed to identify and characterize T-cell or B-cell recognition sites within tumor-associated antigens. By providing a defined antigenic sequence, it enables researchers to pinpoint regions of immunological relevance, facilitating the dissection of immune recognition patterns. Such studies are critical for understanding the molecular determinants of immune specificity and for guiding the rational design of targeted immunotherapies or diagnostic reagents.

T-Cell Activation Assays: In cellular immunology, this peptide serves as a model antigen for stimulating T-cells in vitro to assess antigen-specific activation, proliferation, or cytokine release. Researchers utilize it in assays such as ELISPOT, intracellular cytokine staining, or flow cytometry-based proliferation studies to evaluate the functional responsiveness of T-cells. These applications are particularly valuable for profiling immune responses in preclinical models, optimizing conditions for immunogenicity testing, and characterizing the repertoire of T-cell receptors involved in tumor antigen recognition.

Immunoassay Development: The defined sequence of NY-CO-13 (103-111) supports its use in the development and validation of immunoassays, including peptide-based ELISAs and antibody screening platforms. Its application in these assays allows for the quantification of antigen-specific antibodies or the detection of immune effector cells in various biological samples. Such tools are instrumental in monitoring immune responses during research studies, quality control of immunological reagents, and the standardization of assay protocols for translational investigations.

Peptide Vaccine Research: The NY-CO-13 (103-111) peptide is also utilized in the context of experimental peptide vaccine studies, where it serves as a prototype antigen for evaluating immunogenicity and antigen processing. Its incorporation into vaccine formulations or immunization protocols allows researchers to assess the generation of antigen-specific immune responses, investigate adjuvant effects, and optimize delivery strategies. These experimental approaches contribute to the broader understanding of peptide-based immunization and the identification of candidate epitopes for future vaccine development.

Antigen Processing and Presentation Studies: Researchers employ this peptide to investigate the mechanisms of antigen processing and presentation by major histocompatibility complex (MHC) molecules. By using defined peptide fragments, scientists can dissect the requirements for peptide binding, loading, and presentation on the cell surface, which are fundamental processes in adaptive immunity. Such studies provide insights into the molecular interactions governing antigen display, inform the selection of immunogenic epitopes, and enhance the design of next-generation immunotherapeutic strategies.
