Description: Biotin-Ova (323-339) is the N-ter biotinylated version of Ova (323-339). Biotin-Ova (323-339) can be used in the analysis of antigen-specific T cells. Ovalbumin protein: Ova (323-339) is an epitope of interest of the egg white albumen, which is widely used in allergy research. Ovalbumin is a glycoprotein that is sufficiently large and complex to be mildly immunogenic. Indeed, it has been demonstrated that Ovalbumin contains B-cell epitopes which are recognized by specific IgE antibodies and CD4 T cell epitopes restricted by the MHC I-Ad molecule in mice and by HLA-D molecule in human.Applications of Ova (323-339):Ova (323-339) allows to study bindings of class II MHC-peptide and T-cell activation in PBMCs by ELISPOT assays. In fact, this method quantifies peptide epitope specificity and IFN-γ releasing effector cells. It has been shown that Ova (323-339) was responsible for 25-35% of T-cell response of isolated BALB/c mouse. An investigation has demonstrated that Ova and Ova (323-339) induced similar lung inflammation and a Th2-like dominant immune response in mouse model. Sequence: Biotin-ISQAVHAAHAEINEAGR

Description: Biotin-FluM1 (58-66) is the N-ter biotinylated version of FluM1 (58-66). Biotin-FluM1 (58-66) can be used in the analysis of antigen-specific T cells.FluM1 (58-66):FluM1 (58-66) is a short part of the matrix protein of Influenza A virus which is the most abundant component of this enveloped virus localized under the viral lipid envelope. The GILGFVFTL epitope is highly conserved in Influenza A virus strains at a rate of 93% for 69 strains tested. Human Influenza epitopes may bind MHC molecules and then may be recognized by CD8+ cytotoxic T cells. Applications of FluM1 (58-66):FluM1 (58-66) is used to stimulate CTL responses in peripheral blood mononuclear cells (PBMCs). Then, ELISPOT assay is used to quantify peptide epitope specificity and IFN-γ releasing effector cells.FluM1 (58-66) has shown CTL responses qualified of immunodominant with restriction by HLA-A*02:01. It has also been detected CTL responses when FluM1 (58-66) is restricted by all HLA-C. Therefore, FluM1 (58-66) may help to understand the reaction of immune system against Influenza virus of each populations having different HLA type.FluM1 (58-66) has indeed prompted research to develop T-cell vaccine strategies capable of inducing specific CTL responses in patients upon immunization with Influenza M1 antigenic epitope. MVA-NP+M1 vaccine use GILGFVFTL epitope and is tested in clinical trial.Potential cross-reactivity with HIV-1 p17 Gag (77-85):Moreover, FluM1 (58-66) share similarities with HIV-1 p17 Gag (77-85) which can potentially show a cross-reactivity between these epitopes. It has been demonstrated a cross-reactivity and results suggest that immunity following infection by Influenza virus causes specific immune response to HIV-1 p17 Gag (77-85).Sequence: Biotin-GILGFVFTL

Description: Biotin-MAGE-A1 (278-286) is the N-ter biotinylated version of MAGE-A1 (278-286). Biotin-MAGE-A1 (278-286) can be used in the analysis of antigen-specific T cells. MAGE-A1 protein:MAGE-A1 (278-286) is an epitope of Melanoma Antigen Gene A1 expressed by tumors of different histological types such as on the surface of breast carcinoma cell and is a Cancer/Testis Antigens (CTA). MAGE-A1 is a tumor antigen expressed in 40% of melanoma and contains epitope for binding HLA-A*02:01 molecules and that are recognized by cytotoxic T cells. Applications of MAGE-A1 (278-286): MAGE-A1 (278-286) is used to stimulate specific cytotoxic T cells in PBMCs and to analyze by ELISPOT peptide epitope specificity and cytokine production like IFN-γ. Immunogenicity of MAGE-A1 (278-286) raised the possibility of developing anticancer immunotherapies or vaccinations. MAGE-A1 is also expressed in lung adenocarcinoma and studies suggest that MAGE-A1 may serve to develop Chimeric Antigen Receptor (CAR) T cell therapy using lentiviral vector and show an encouraging tumor-inhibitory efficacy.Sequence: Biotin-KVLEYVIKV

Description: Biotin-MAGE-A2 (157-166) is the N-ter biotinylated version of MAGE-A2 (157-166). Biotin-MAGE-A2 (157-166) can be used in the analysis of antigen-specific T cells. MAGE-A2 protein: MAGE-A2 (157-166) is an epitope of Melanoma Antigen Gene A2 and is one of the most Cancer-Testis Antigens (CTA) overexpressed in tumors of different histological types, such as prostate cancer. Type of MAGE-A expressed in tumors cells varies according to the type of tumor. The expression of MAGE-A2 causes the proliferation of prostate cancer cells and decreases the chemosensitivity. Applications of MAGE-A2 (157-166):MAGE-A2 (157-166) is used to stimulate specific immune response, cytotoxic T cell response and to analyze the cytokine production in PBMCs by ELISPOT assay. In transgenic mouse, it has been demonstrated that MAGE-A2 (157-166) was capable of eliciting a CTL response presented by HLA-A*02:01 molecules. MAGE-A2 (157-166) has been reported to elicit CTL that could lyse tumor cell expressing both HLA-A*02:01 and MAGE-A2 by stimulation of peripheral blood mononuclear cells (PBMCs) with MAGE-A2 (157-166).Sequence: Biotin-YLQLVFGIEV

Description: Biotin-NY-ESO-1 (157-165) – General analog epitope of tumor cellsBiotin-NY-ESO-1 (157-165) C165V peptide is the N-ter biotinylated version of NY-ESO-1 (157-165) C165V peptide. It can be used in the analysis of antigen-specific T cells. 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 the scrambled version of NY-ESO-1 (157-165) C165V peptide, as well as NY-ESO-1 (157-165) native peptide.
