Description

SB-peptide offers the scrambled MSILWQLVT peptide that can be used as a negative control of NY-ESO-1 (157-165) C165V variant epitope studies.

SB-peptide also offers NY-ESO-1 (157-165) C165V (see section NY-ESO-1 (157-165) C165V).

HLA-A*02 Major Histocompatibility Complex (MHC) allele

HLA-A*02 allele is expressed in class I Human MHC Leukocyte Antigens (HLA), that are cell surface receptors, presenting peptides to the immune system. If a non-self-peptide is recognized by cytotoxic T-cells in the blood, cell death will be initiated via apoptosis.

NY-ESO-1 protein

Peptides presented by MHC class I molecule, are usually between 7 and 11 amino acids, originating from proteins expressed by the cell. SLLMWITQV peptide differes from the New York esophageal squamous cell carcinoma 1 (NY-ESO-1 : UniProt - P78358) native SLLMWITQC peptide, whose protein is part of a well-characterized group of cancer/testis antigens (CTAs).

Normally, NY-ESO-1 expression is restricted to germ cells and placental cells. However it is also expressed in 82% of neuroblastomas and 46% of melanomas, as well as in many other solid tumors and hematological malignancies.

NY-ESO-1 (157-165) C165V peptide application

Class I HLA molecules of the cancerous cells cited above present peptides from NY-ESO-1 protein, including SLLMWITQC, that binds the binding cleft of the HLA-A*0201 complex. NY-ESO-1 being the most immunogenic among the CTA family members, its peptides constitute attractive targets for specific immunotherapies and the stimulation of human NY-ESO-1 specific CD8+ T cells.

In order to better stimulate specific cytotoxic T-cells in PBMCs and analyze by ELISPOT peptide epitope, specificity, and cytokine production, like IFN-γ, SLLMWITQV variant peptide was used, as it is known to have a higher affinity for the binding cleft of the HLA-A*0201 complex than the native peptide. Moreover, SLLMWITQV has been used with adjuvant in protein nanoparticles in order to study cell-mediated immune responses and is also used in clinical trial to study the immunological effects of vaccines containing NY-ESO-1 (157-165) C165V.

SB-PEPTIDE also offers NY-ESO-1 (157-165) native peptide, as well as Biotin-NY-ESO-1 (157-165) C165V.
