Gp100 (25–33), mouse TFA（Cat No.:I044276）is a synthetic nonapeptide derived from residues 25 to 33 of the mouse gp100 protein, a melanocyte differentiation antigen. This peptide is widely used in immunological research, particularly in melanoma models, as it is recognized by cytotoxic T lymphocytes (CTLs) and helps in studying antigen-specific immune responses. It plays a crucial role in cancer immunotherapy research, especially for evaluating T cell activation and tumor targeting. The TFA (trifluoroacetate) form indicates the peptide is provided as a trifluoroacetate salt, commonly used for stabilization and storage.
