Merck, H3663-200UL, Anti-HA antibody, Mouse monoclonal

Hemagglutinin (HA) is a glycoprotein present in the membrane of influenza virus. HA exists as a trimer and each monomer at its membrane tip has receptor-binding site. Glycosylation event of HA occurs in endoplasmic reticulum. The head region with the receptor-binding site of the HA is variable. The mouse monoclonal Anti-HA, Clone HA-7 recognizes the human influenza virus hemagglutinin (HA), known as the HA tag. The product is reactive with HA-tagged fusion proteins expressed at either the amino or the carboxy terminus of the fusion protein.
