YPYDVPDYAGEFKQEDMIEIVDILMMQ

YPYDVPDYAGEFKQEDMIEIVDILMMQ is a synthetic HA epitope-tag-containing peptide. This product contains the influenza hemagglutinin-derived HA epitope YPYDVPDYA. The HA tag is a short linear epitope widely used for antibody-based visualization, detection, localization, and biochemical characterization of tagged proteins.

• anti-HA antibody binding and competition assays
• epitope-tag detection controls
• immunochemical method development
• tag accessibility studies

The behavior of a motif embedded in a longer peptide can differ from the isolated tag or parent sequence. Flanking residues, linkers, phosphorylation, fluorophores, affinity handles, cyclization, and terminal modifications may alter accessibility, binding, uptake, or assay performance.
