NY-ESO-1 157-165 mutant (HLA-A*02:01) 165V SLLMWITQV
€210.00*
Description
The peptide NY-ESO-1 157-165 mutant 165V with the amino acid sequence SLLMWITQV (IEDB epitope ID 59283) is a modified linear epitope derived from the human Cancer/Testis Antigen 1 (NY-ESO-1; UniProt ID: P78358). This specific variant, often referred to as the 165V analog, features a C-terminal substitution of Cysteine to Valine.
This modification is widely used in cancer immunotherapy research to improve the stability of the peptide-MHC complex. As a heteroclitic peptide, SLLMWITQV often demonstrates enhanced binding affinity to HLA-A*02:01 compared to the wild-type sequence, making it a critical tool for expanding and detecting NY-ESO-1 specific CD8+ T-cells.
Scientific Significance & Applications
The SLLMWITQV analog is one of the most extensively studied peptides in tumor immunology:
Enhanced Immunogenicity: Studied for its ability to elicit stronger T-cell responses than the native sequence, making it a prime candidate for cancer vaccine development and TCR-T cell priming.
Comprehensive Validation: Heavily documented in T-cell assays, B-cell assays, and MHC ligand binding studies.
Precision Tool: Ideal for the stimulation, identification, and sorting of NY-ESO-1 specific CD8+ T-lymphocytes.
Part of an Immunodominant Cluster
This peptide is a key component of the highly immunogenic NY-ESO-1 157-170 cluster. This region is recognized by multiple HLA alleles, allowing for comparative immunological studies:
- NY-ESO-1 157-165 (SLLMWITQC): The native HLA-A*02:01 Wild-Type.
- NY-ESO-1 158-166 (LLMWITQCF): Optimized for HLA-A*24:02.
- NY-ESO-1 162-170 (ITQCFLPVF): Targeted for HLA-B*15:17.
