Anti-HA antibodies are useful for the immunodetection of HA, or hemagglutinin which is a surface glycoprotein that causes agglutination. The hemagglutinin epitope tag, or HA-tag, is derived from the human influenza hemagglutinin and is commonly attached to recombinant proteins for detection and purification. The 10-residue peptide (YPYDVPDYA) binds to specific anti-HA antibodies. To search for specific applications, reactivities or host species simply check the filter boxes in the left column.
