HA tag (7H5) Monoclonal Antibody

Plasmid vectors for the expression of coding regions of eukaryotic genes in bacterial, insect and mammalian hosts are in common usage. The expression vectors are used to encode hybrid fusion proteins consisting of a eukaryotic target protein and a specialized region designed to aid in the purification and visualization of the target protein. Short pieces of welldefined peptides (Poly-His, Flag-epitope or cmyc epitope or HA-tag) or small proteins (bacterial GST, MBP) is often cloned along with the target gene. The HA tag is derived from an epitope of the influenza hemagglutinin protein, which has been extensively used as a general epitope tag in expression vectors. It has been successfully used in a variety of applications, including Western blotting, Immunoprecipitation, and immunofluorescence studies.
