What is OVA-T4 Peptide?
OVA-T4 Peptide (sequence SIITFEKL) is a synthetic peptide derived from the ovalbumin (OVA 257–264) epitope. It is a modified version of the well-known SIINFEKL sequence, used as a class I MHC (H-2K^b) restricted epitope in immunological research. This peptide activates CD8⁺ T cells and is widely applied in studies involving T cell receptor sensitivity, immune response modulation, and vaccine development using the OT-I T cell model.
