OVA (323-339), 5-TAMRA-Labeled

OVA(323-339) is a classic ovalbumin-derived CD4 T-cell epitope widely used with the murine I-A(d) and I-A(b) MHC class II systems. This version carries an N-terminal 5-TAMRA fluorophore, enabling visualization of peptide uptake, antigen handling and related immunological processes.

OVA(323-339) is a class II epitope; it should not be described as the H-2Kb class I epitope. Fluorophore conjugation can influence peptide uptake and MHC loading, so use appropriate unlabeled controls.
