Background
Influenza Hemagglutinin (HA) Peptide is a synthetic peptide with the amino acid sequence Tyr-Pro-Tyr-Asp-Val-Pro-Asp-Tyr-Ala (YPYDVPDYA), derived from residues 98-106 of the HA1 subunit of the human influenza virus hemagglutinin (HA) protein[1]. Influenza Hemagglutinin (HA) Peptide commonly used in immunoprecipitation (IP) and affinity purification experiments as a competitive elution agent. By adding it in excess, Influenza Hemagglutinin (HA) Peptide allows for the gentle elution of HA-tagged fusion proteins in their native state, avoiding the damage to protein activity caused by harsh conditions such as low pH or denaturants[2, 3]. Influenza Hemagglutinin (HA) Peptide can also be used to isolate HA-tagged fusion proteins from monoclonal anti-HA agarose affinity columns[4].
