This monoclonal antibody was clarified from mouse ascitic fluid and is specific for H5 hemagglutinin (HA) protein of influenza A virus [strain A/Vietnam/1203/04 (H5N1)]. VN04-9 monoclonal antibody did not cross-react with influenza viruses of other HA subtypes. It reacted with H5N1 influenza virus representatives of different clades and subclades of the H5 HA subtype.

Target Information

Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA. In early 2009, a novel swine-origin influenza A (H1N1) virus was identified in specimens obtained from patients in Mexico and the United States. The virus spread globally, leading the World Health Organization to declare a pandemic on June 11, 2009.

Influenza A virus has one of sixteen possible Hemagglutinin (HA) surface proteins and one of nine possible Neuraminidase (NA) surface proteins. The HA protein facilitates viral attachment, while NA is involved in viral release. These proteins elicit immune responses that prevent infection or reduce viral replication.

The genetic make-up of the swine flu virus is unique: it is an H1N1 strain combining human, swine, and avian influenza genes with new pig H3N2 genes from Eurasia. The distinct antigenic properties of this virus suggest limited human immunity, though older age groups may have partial protection.
