  • Description
    Rabbit polyclonal to Avian Influenza A Hemagglutinin
  • Host species
  • Specificity
    Rabbit anti-Hemagglutinin (IN) protein polyclonal antibody was raised against a synthetic peptide corresponding to 14 amino acids in the middle of the Hemagglutinin protein (Genbank accession no. AAT76166). Efforts were made to use relatively conserved regions of the viral sequence as the antigen. The antibody only recognizes the full-length H5, not the cleaved subunit.
  • Tested applications
    Suitable for: ELISAmore details
  • Species reactivity
    Reacts with avian Influenza A virus.
  • Immunogen

    A synthetic peptide corresponding to 14 amino acids from an internal sequence of the Hemagglutinin protein conjugated to KLH.



Our Abpromise guarantee covers the use of ab21292 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use a concentration of 1 µg/ml. to detect 10 ng of free peptide.


  • Relevance
    Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA. Novel influenza virus strains caused by genetic drift and viral recombination emerge periodically to which humans have little or no immunity, resulting in devastating pandemics. Influenza A can exist in a variety of animals; however it is in birds that all subtypes can be found. These subtypes are classified based on the combination of the virus coat glycoproteins hemagglutinin (HA) and neuraminidase (NA) subtypes. HA interacts with cell surface proteins containing oligosaccharides with terminal sialyl residues. Virus isolated from a human infected with the H5N1 strain in 1997 could bind to oligosaccharides from human as well as avian sources, indicating its species-jumping ability.
