The HA tag (hemagglutinin tag) is a short epitope sequence derived from the influenza virus hemagglutinin surface glycoprotein. It is widely used as a fusion tag to facilitate the detection, localization, and purification of recombinant proteins in various expression systems. When incorporated into a protein of interest, the HA tag enables:
-Protein Localization Studies – Tracking the distribution of tagged proteins within cells.
-Topology and Complex Analysis – Investigating protein structure, orientation, and interaction networks.
-Protein-Protein Interaction Mapping – Identifying associated proteins through co-immunoprecipitation.
-Characterization of Novel or Low-Abundance Proteins – Providing detection capability when specific antibodies are unavailable or the protein is poorly immunogenic.
This monoclonal antibody specifically recognizes the HA epitope and is ideal for applications such as Western blotting, immunofluorescence, immunoprecipitation, and ELISA. It offers high sensitivity and specificity for both native and denatured forms of HA-tagged proteins, ensuring reliable results in research and protein characterization workflows.
