NY-ESO-1 162-170 (HLA-B*15:17) ITQCFLPVF
€105.00*
Description
The peptide NY-ESO-1 162-170 (ITQCFLPVF) is a linear nonamer derived from the human Cancer/Testis Antigen 1 (NY-ESO-1; UniProt: P78358). This specific sequence is a key tool for researchers investigating T-cell responses restricted to the HLA-B*15:17 allele.
As part of the immunodominant cluster spanning residues 157 to 170, this peptide allows for the precise mapping of CD8+ T-cell activity at the C-terminal boundary of this highly reactive region.
Scientific Significance
While many studies focus on HLA-A*02, the inclusion of B-allele restricted epitopes is essential for a complete understanding of tumor-specific immunity:
- Epitope Cluster Integration: This peptide overlaps with the "Gold Standard" 157-165 region, providing a critical perspective on how different HLA molecules (A vs. B alleles) compete for or share overlapping sequences.
- Allele-Specific Research: Optimized for use in cohorts where HLA-B*15:17 is a relevant genetic background, ensuring that no T-cell response remains undetected due to limited HLA-coverage.
- Structural Studies: Ideal for investigating the binding motifs and stability of the HLA-B*15 family when presenting NY-ESO-1 derived peptides.
Applications
- Advanced Epitope Mapping: Defining the exact C-terminal reach of T-cell recognition within the NY-ESO-1 157-170 hotspot.
- T-Cell Assay Control: Use as a specific positive control in IFN-$\gamma$ ELISpot or intracellular cytokine staining (ICS) for HLA-B*15:17 positive samples.
- Multi-Allele Screening: A necessary component for "Pan-HLA" screening panels to ensure comprehensive immune monitoring in clinical trials.
