Immunohistochemistry: HA Tag Antibody [NB600-362] - SUMO1 conjugates are not localized to amyloid plaques. (a) Sagittal brain sections of 24-week-old KI/AD and WT/AD animals were stained using anti-HA antibodies (red), 6E10 antibodies (green) that label amyloid beta 1-42 among other amyloid beta variants (epitope lies within amino acids 3-8 of amyloid beta) and anti-MAP2 antibodies (blue). Sections of the hippocampal subiculum are shown. Images are representatives of three independent experiments. Scale bar, 25 um.

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).
