Influenza is a respiratory infection in mammals and birds and is caused by an RNA virus of the Orthomyxoviridae family. There are four main types of influenza virus (Influenza A, Influenza B, Influenza C, Influenza D), which are distinguished by variations in two important internal proteins (hemagglutinin (HA) and neuraminidase (NA)).
Types A, B, and C of the influenza viruses can infect humans. There is no evidence to date that humans can become infected with type D. However, this type is thought to have the potential to do so.
Seasonal epidemics can be caused by Influenza A and B. However, only type A has caused global pandemics, such as the pandemic H1N1 virus in 2009. To prevent further pandemics, it is very important to support the influenza research and development. Therefore, trenzyme has produced the HA1 subunit of the hemagglutinin protein (HA) from the Influenza A - G4 (EA) H1N1 virus. This plays an important role in the infection of a cell and is therefore a major target for antibody test development or vaccine development. The production of further influenza proteins is planned.
