Background: HA Tag

Human influenza hemagglutinin (HA) is a glycoprotein required for the infectivity of the human virus and is expressed as a homotrimer on the surface of the viral capsid (1). As a major antigen of the influenza virus, HA constantly evolves to escape herd immunity via antigenic shift which can lead to pandemics (2). The HA tag (YPYDVPDYA-tag) itself has a molecular weight of 1.1 kDa and is a linear epitope derived from amino acids 98-106 of the HA protein. It is used extensively as a general epitope tag in expression vectors (2, 3). The HA tag is frequently added to the N- or C- terminus of a protein of interest to facilitate protein purification, detection, and labeling using anti-HA antibodies (3, 4). HA Tag is cleaved by caspase 3/7 resulting in total loss of immunoreactivity, making it unsuitable for the study of apoptosis (5).
