Description: Rabbit Polyclonal Antibody

Specificity: Anti-HA antibody recognizes the N-terminal, C-terminal or internal HA-tagged (YPYDVPDYA sequence) fusion protein

Cited Applications: ELISA, WB, IP, IS

Cross Reactivity: All proteins tagged with HA

Host / Isotype / Clone#: Rabbit Polyclonal

Formulation: TBS at pH 7.2, 50% glycerol

Purification: Purified by antigen-specific affinity chromatography

Stability: Store at 4°C (add 0.1% NaN₃) for several months, and at -20°C for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Scientific Background: The HA epitope tag (YPYDVPDYA) consists of 9 amino acid residues and comes from the Human influenza virus hemagglutinin [1]. Hemagglutinin is a viral cell surface glycoprotein responsible for the binding of viral particles to their target cell, and is named because of its ability to agglutinate erythrocytes in vitro [2].
