Uty HY Peptide (246–254) (TFA)（Cat No.:I044305）is a synthetic nonapeptide corresponding to amino acid residues 246 to 254 of the murine Uty gene, which encodes a minor histocompatibility antigen located on the Y chromosome. This peptide is presented by MHC class I molecules and recognized by CD8⁺ T cells, playing a role in immune responses against male cells in female recipients, particularly in transplantation and graft-versus-host disease (GVHD) models. The TFA (trifluoroacetate) salt form enhances peptide stability and solubility, making it suitable for use in immunological and transplantation tolerance research.
