Scientific Data Images for HA Tag Antibody

Detection of HA-tagged proteins antibody by Western Blot.

Detection of HA-tagged proteins by Western Blot.

Western blot shows lysates of HEK293 human embryonic kidney cell line transfected with N-terminal HA-tagged LGI-2, Internal Sequence HA-tagged CIGALT, and C-terminal HA-tagged FBLN. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-HA Peptide Monoclonal Antibody (Catalog # MAB6875) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). Specific bands were detected for HA-tagged proteins at approximately 60, 37, and 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

HA Tag in HEK293 Human Cell Line.

HA Tag was detected in immersion fixed HEK293 human embryonic kidney cell line using Mouse Anti-HA Tag Monoclonal Antibody (Catalog # MAB6875) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

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).
