Anti-Influenza A, Matrix Protein [E10] Antibody

The E10 monoclonal antibody was generated against a matrix protein 2 (M2) extracellular domain peptide-KLH conjugate and is specific for matrix proteins 1 and 2 (M1 and M2) of all Influenza A viruses. The antibody has been tested via WB, ELISA, IHC, and FCM experiments.


  • Reacts with Influenza A Matrix Protein 1 (M1) and 2 (M2)
  • Suitable for Western Blot, ELISA, Immunohistochemistry and Flow Cytometry applications

Influenza A virus is an enveloped virus encoding 10 polypeptides. RNA segment 7 encodes for two proteins: matrix 1 (M1) and matrix 2 (M2). The M1 protein is critical for assembly and budding, interacting with the influenza hemagglutinin (HA) and neuraminidase (NA) proteins. M2 protein is a transmembrane protein composed of three domains: a 24 residue domain representing the N-terminal region, a 19 hydro-phobic residue domain that serve as a membrane anchor, and a 54 residue domain near the C-terminal in the cytoplasmic domain. The M2 protein has been found to play a role in Influenza replication and assembly of virion particles. It has been shown that this protein is an acid-activated ion channel for virus replication.
