Influenza A HA 116-131 Peptide YDVPDYASLRSLVASS
€133.20*
Description
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.
