HA Peptide TFA (Cat No.:I044772) is an epitope tag derived from the human influenza virus hemagglutinin protein. Commonly used in molecular biology and biotechnology, it enables detection, purification, and localization of tagged recombinant proteins. The peptide is specifically recognized by HA-tag antibodies, facilitating applications such as Western blotting, immunoprecipitation, and immunofluorescence. Supplied as a trifluoroacetate (TFA) salt, the HA peptide offers excellent solubility and stability. Its small size minimizes interference with protein function, making it a preferred tag in protein expression and functional studies across diverse biological systems.
