Influenza Virus Influenza B Nucleoprotein
(tested or 100% immunogen sequence identity)
Influenza B/Lee/40 and B/Singapore/-222/79 viruses.
Recognizes a species specific conserved epitope within the nucleoprotein of influenza B virus. The influenza viruses, classified as type A, B and C, are members of the Orthomyxoviridae family which differ in their epidemiology and host ranges and lack serological cross-reactivity of their internal components, especially their matrix proteins and nucleoprotein. Influenza B virus is a slow-mutating single stranded RNA virus subject to antigenic drift which, although enough to prevent lasting immunity, prevents influenza B from causing pandemics. Can be used in influenza B IFA typing.
