Hemagglutinin Monoclonal Antibody
Background
Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA (1). 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 (2). These subtypes are classified based on the combination of the virus coat glycoproteins hemagglutinin (HA) and neuraminidase (NA) subtypes. During 1997, an H5N1 avian influenza virus was determined to be the cause of death in 6 of 18 infected patients in Hong Kong (3). The more recent virulent strain of H5N1 is now seen in Africa and Europe, as well as in southeast Asia. There is some evidence of human to human spread of this virus, but it is thought that the transmission efficiency was fairly low (4). 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 (5). While efforts were made to use relatively conserved regions of the viral sequence as the antigen, the influenza virus genome has drifted somewhat from what was first reported. However, this antibody was able to recognize peptides derrived from viruses from Indonesian human patients infected in 2007.

Source
Mouse monoclonal Hemagglutinin antibody was raised against a synthetic peptide corresponding to 13 amino acids in the middle of the Hemagglutinin protein. This sequence is identical to the immunogen of the polyclonal AFHA-3 antibody 3911.
Purification
Immunoaffinity chromotography purified IgG
Clonality / Clone
This is a monoclonal antibody. (Clone 1E7D8)
Host
Hemagglutinin monoclonal antibody was raised in mouse.
Please use anti-mouse secondary antibodies.
Immunogen
A peptide corresponding to 13 amino acids in the middle of the Hemagglutinin protein.
Application
Hemagglutinin antibody can be used for the detection of the Hemagglutinin protein from the H5N1 strain of avian influenza A in ELISA. (Optimal dilution should be determined by user.) It will detect 10 ng of free peptide at 1 μg/ml. Other applications are pending.
