Antigen Peptide Myeloblastin precursor HLA-A*0201 (VLQELNVTV) for stimulation of human Proteinase 3-specific CD8+ T-cells. The peptide is synthesised as it is presented by the MHC class I HLA-A*0201 allele. PR1 (VLQELNVTV) is a human leukocyte antigen-A2 (HLA-A2)-restricted leukemia-associated peptide from proteinase 3 (P3) and neutrophil elastase (NE) that is recognized by PR1-specific cytotoxic T lymphocytes that contribute to cytogenetic remission of acute myeloid leukemia (AML). VLQELNVTV is a linear peptidic epitope (epitope ID69719) studied as part of Myeloblastin from Homo sapiens (human). This epitope has been studied for immune reactivity, tested in T cell assays, B cell assays and MHC ligand assays
