Description_x000D_ General description_x000D_ The hemagglutinin (HA) gene is mapped to segment 4 of Influenza B viral genome. HA is a dominant antigen present on the influenza viral surface. HA is a homotrimer, in which each monomer is produced as a single polypeptide. This monomer is cleaved into two subunits HA1 and HA2 by the host protease. Influenza hemagglutinin protein is a nona-peptide derived from the major spike membrane glycoprotein of the human influenza virus. This strain specific glycoprotein is a homotrimer of 84kDa monomers._x000D_ Immunogen_x000D_ The immunogen used to generate this antibody corresponds to HA tag_x000D_ Application_x000D_ Suggested starting dilutions are as follows: ICC/IF: 1:100-1:2000, IP: 1:100-1:500, WB: 1:1000-1:10000. Not yet tested in other Application Longs. Optimal working dilutions should be determined experimentally by the end user.Monoclonal Anti-HA tag antibody produced in mouse has been used in western blot analysis._x000D_ Physical form_x000D_ Phosphate-buffered saline, no preservative added._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Hemagglutinin (HA) is an influenza-virus glycoprotein that regulates membrane fusion and receptor-binding functions during viral entry and infection. The virus gains entry into the host cell via endocytosis and successive membrane fusion mediated by the HA antigen. HA plays a crucial role in viral pathogenesis and host response to viral infection._x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
