SLLMWITQC - The Essential Benchmark for Precision Immunotherapy
SLLMWITQC is not just another epitope—it is one of the most thoroughly characterized HLA-A*02:01 restricted sequences (epitope ID59278) in cancer immunology. Derived from both Cancer/testis antigen 1 (NY-ESO-1; UniProt: P78358) and the LAGE-1A isoform of Cancer/testis antigen 2 (UniProt: O75638-2), this peptide offers unique dual-targeting potential. It is the essential specialist tool for anyone developing or validating therapies aimed at these potent human tumor antigens.
Why this Peptide is Your Essential Specialist Tool
This peptide is the specific positive control to show if your anti-cancer weapon is functional.
- Validate Your TCR-T Cells: Use SLLMWITQC to verify that your engineered T-cell receptors correctly recognize and react to their target.
- Benchmark Vaccine Success: A critical reference to monitor if your vaccine has successfully primed an antigen-specific immune response.
- Eliminate Assay Guesswork: As a high-affinity binder, it provides a reliable "on" signal, ensuring that your detection system (ELISpot, ICS, or Multimer staining) is working perfectly.
Proven Performance, IEDB-Validated
With over 500 validated T-cell assays and 85+ publications, SLLMWITQC is a trusted sequence for:

Reported in 6 peer-reviewed publications
Tested in 7 T cell assays, demonstrating strong CD8⁺ T cell reactivity
Assessed in 1 B cell assay and 2 MHC ligand assays
Background on NY-ESO-1 and CTAs
NY-ESO-1 is one of the most immunogenic cancer/testis antigens (CTAs). CTAs are normally expressed only in germ cells of the testis but become aberrantly re-expressed in many cancers, including melanoma, lung, ovarian, and esophageal tumors. Because the testis is an immune-privileged site, the immune system does not develop tolerance to these antigens—making them highly attractive targets for cancer immunotherapy and immune monitoring.
These characteristics have positioned NY-ESO-1, and epitopes like RLLEFYLAM, at the center of research into cancer vaccines, adoptive T cell therapies, and diagnostic assays.

This nonamer peptide (IEDB epitope ID: 2265540) is restricted to HLA-B*07:02 and has been investigated for its role in antigen-specific T cell responses in cancer immunology.
NY-ESO-1 and CTAs
NY-ESO-1 belongs to the family of cancer/testis antigens (CTAs), proteins typically restricted to germ cells of the testis but aberrantly expressed in many tumors, including melanoma, lung, ovarian, and esophageal cancers. Because of this unique expression profile and their strong immunogenicity, CTAs like NY-ESO-1 are widely recognized as prime targets for cancer immunotherapy, immune monitoring, and vaccine development.
NY-ESO-1 epitopes such as AMPFATPME contribute to dissecting CD8⁺ T cell responses and advancing the development of diagnostic assays and adoptive T cell therapies.

Comprehensive Antigen Scan for Complete T-Cell Profiling
The NY-ESO-1 Peptide Pool from peptides&elephants is a high-performance tool designed for the thorough analysis of T-cell responses against Cancer/Testis Antigen 1 (NY-ESO-1).
Unlike focused sub-pools, this comprehensive pool consists of 43 overlapping peptides (15-mers with an 11-amino acid overlap) spanning the entire length of the NY-ESO-1 protein (UniProt ID: P78358). The peptide scan approach ensures that no potential epitope is missed, making it the ideal tool for screening both CD4+ and CD8+ T-cell responses regardless of the donor's HLA type.
The NY-ESO-1 Peptide Pool is optimized for T-cell assays such as ELISpot, ICS and Flow Cytometry.
Why Use a Full Antigen Scan?
The 15-mer overlapping strategy is the most robust method for immunological profiling:
Unbiased Discovery: Identifies all relevant epitopes across the entire protein sequence.
Dual Activation: The 15-amino acid length is ideal for presentation on both MHC Class I and Class II molecules, activating both CD8+ and CD4+ T-cells.
HLA-Independent: Suitable for use with any donor sample, as it covers all possible HLA-restricted motifs.
Applications & Scientific Validation
This peptide pool is a staple in clinical cancer research and immune monitoring. Its efficacy in detecting tumor-specific immune responses has been demonstrated in various high-impact studies.
