Application: HA Tag Peptide is a short epitope sequence derived from influenza virus hemagglutinin, a viral protein involved in host-cell receptor attachment. Because of its small size and strong immunoreactivity, the HA tag is widely used in recombinant protein expression systems as a general epitope tag. Fusion with the HA tag typically does not disrupt protein activity, localization, or biodistribution, while enabling efficient detection with anti-HA antibodies. HA Tag Peptide is commonly used in protein tracking, immunodetection, western blotting, immunoprecipitation, localization studies, and recombinant protein analysis, though caspase cleavage may limit apoptosis applications.
