OVA (257–264), Scrambled(CAT: I040732) is a control peptide featuring a randomized amino acid sequence of the well-known OVA (257–264) epitope from ovalbumin. Unlike the native SIINFEKL sequence, this scrambled version does not effectively bind to MHC class I molecules, making it an ideal negative control in T-cell activation and antigen presentation assays. It is widely used to validate the specificity of CD8+ T cell responses in immunological studies, particularly in murine models. Suitable for ELISPOT, flow cytometry, and cytotoxicity assays, this peptide ensures reliable experimental controls in vaccine development and immune profiling.
