HA Tag antibodies

2742mousemonoclonal (HA.C5)IgG3WBICCELISA

The HA tag, derived from the human influenza hemagglutinin protein, is a widely employed tool in recombinant protein expression and has become an invaluable asset in molecular biology research. When incorporated at the N- or C-terminus of a target protein, the HA tag serves as a short, immunogenic peptide sequence, enabling efficient detection, purification, and characterization of the expressed protein. Its small size minimizes disruption to the target protein’s structure and function, making it suitable for a diverse range of applications. The HA tag is specifically recognized by commercially available high-affinity antibodies, facilitating the precise and sensitive detection of the tagged protein in techniques like Western blotting and immunofluorescence. Additionally, the HA tag is compatible with affinity chromatography, enabling straightforward and effective purification of the tagged protein from complex cellular extracts.
