Description

The Influenza A HA 322–333 Peptide (PKYVKQNTLKLA) is a well-characterized 12-mer linear CD4+ T-cell epitope derived from the HA1 subunit of Influenza A Hemagglutinin (strain A/Aichi/2/1968 H3N2; UniProt-ID: P03437).

Specifically restricted to HLA-DRA*01:01 / DRB1*01:01 (HLA-DR1), this sequence is utilized in cellular immunology to evaluate CD4+ T-cell reactivity, MHC-peptide binding dynamics, and cross-reactive recall responses against seasonal H3N2 strains. Indexed under IEDB Epitope ID 48231, this sequence has been validated in peer-reviewed publications across functional T-cell activation assays and direct MHC ligand binding studies. It serves as a targeted reference peptide for epitope mapping, immunomonitoring, and the development of T-cell-directed influenza vaccine strategies.

Influenza A HA 116-131 Peptide

The Influenza A HA 116–131 Peptide (epitope ID 73603) is an extended 16-mer CD4+ T-cell epitope derived from the HA1 subunit of Influenza A Hemagglutinin (H3N2). Binding for this MHC Class II ligand has been experimentally validated for HLA-DRB1*01:01, HLA-DRB1*04:01, and HLA-DRB1*07:01. In canonical UniProt entries such as P03437 for A/Aichi/2/1968 or related H3N2 strains like A/Beijing/32/1992, the sequence YDVPDYASLRSLVASS corresponds to amino acids 116–131 of the precursor protein, which represents residues 98–113 of the mature HA1 chain following signal peptide cleavage.Encompassing the well-known core motif YDVPDYASL, this specific 16-amino-acid sequence has been evaluated in specialized immunological studies (e.g., Gelder et al., 1998) to investigate MHC Class II binding capacity and CD4+ T-cell reactivity. It serves as a targeted peptide for Influenza-specific T-cell assays and epitope characterization.

The Influenza A M1 58-66 peptide is a linear peptidic epitope (epitope ID 20354) that has the amino acid sequence GILGFVFTL and is located at positions 58-66 of the Matrix Protein 1 (UniProt:P03485) from Influenza A virus. The M1 58-66 peptide is highly conserved across many strains of influenza, T cells primed to recognize this peptide can potentially recognize and respond to a variety of influenza infections. This makes the M1 58-66 peptide valuable in vaccine research and in the study of cross-protection against different strains of influenza. The Influenza A M1 58-66 peptide is well-known for its role in being presented by HLA-A*02:01 (a class I MHC molecule) to cytotoxic CD8+ T cells. It is a well-characterized epitope, making it an ideal tool for studying how T cells recognize viral peptides and initiate an immune response. It is used as a model antigen to study T cell function, activation, and the mechanics of antigen presentation. Understanding how immune cells recognize and target antigens also helps improve T cell-based therapies for cancer. The Influenza A M1 58-66 peptide has been tested in T cell assays, B cell assays and MHC ligand assays. It is frequently used as a positive control, especially in ELISPOT and tetramer staining, ensuring that the immune cells are functioning as expected. The M1 58-66 peptide is also a prime example of an immunodominant epitope. In people with the HLA-A*02:01 type, a significant portion of the immune response to influenza focuses on this peptide, making it a key target for understanding immune system priorities in viral infections.See also an example comparison of our prices with the prices of other peptide manufacturers.

Influenza A M1 59-68 (HLA-A*02:01)

The ILGFVFTLTV peptide (epitope ID 27066) overlaps with the well-known immunodominant epitope GILGFVFTL from Influenza A Matrix Protein 1 (M1; UniProt:P03485). Influenza A MP 59-68 is used for the development of more broadly protective influenza vaccines and as a control peptide in immunological studies.Researchers investigated the immunogenicity and protective efficacy of Modified Vaccinia Virus Ankara (MVA) vectors encoding internal influenza antigens in HLA-A2.1 transgenic mice. Following vaccination with recombinant MVAs expressing peptides derived from Influenza A Matrix Protein 1 (M1), the induced CD8⁺ T cell responses were primarily directed against the immunodominant epitope M1 58-66. However, consistent T cell responses were also observed against the overlapping peptide M1 59-68. CD8⁺ T cell activity was assessed using an IFN-γ ELISPOT assay.
