OVA (329–337)（Cat No.:I044262）is a synthetic peptide derived from ovalbumin, corresponding to the amino acid sequence SIINFEKL. It is a well-characterized epitope recognized by murine MHC class I molecule H-2K^b and presented to CD8⁺ cytotoxic T lymphocytes. OVA (329–337) is extensively used in immunology research as a model antigen to study T-cell responses, antigen processing, and vaccine development in mouse models. Its precise immunodominance and compatibility with transgenic T-cell receptor models, such as OT-I mice, make it a valuable tool for investigating cellular immunity, immune tolerance, and antigen-specific immunotherapies.
