Merck, A2095-5X1ML, Monoclonal Anti-HA−Agarose antibody produced in mouse

The HA tag is a 9-amino acid tag, with the sequence YPYDVPDYA (N-Tyr-Pro-Tyr-Asp-Val-Pro-Asp-Tyr-Ala-C), derived from the hemagglutinin (HA) protein at amino acid residues 98-106 in the HA sequence. The HA tag contains a high proportion of charged amino acid residues, which makes the HA tag likely to form a strong antibody recognition site. Monoclonal Anti-HA Agarose Conjugate recognizes native as well as denatured/reduced forms of HA-tagged proteins. This product is reactive with N-or C-terminal HA-tagged fusion proteins that are expressed in E. coli or in mammalian cells.
