Influenza Virus Influenza B Nucleoprotein
(tested or 100% immunogen sequence identity)
Influenza virus type B hemagglutinin.
Specific for Influenza virus type B, a genus in the virus family Orthomyxoviridae, responsible for acute respiratory illnesses in humans. Influenza virus type B varies antigenically from influenza virus types A and C and is not divided into any subtypes. The gradual evolution of Influenza virus type B occurs via a series of mutations known as antigenic drift, in the surface glycoprotein hemagglutinin (HA), enabling the virus to evade the immune system and potentially re-infect the same host. HA glycoproteins from the Influenza virus type B are included in the annually updated trivalent flu vaccine, along with the Influenza virus type A subtypes H3N2 and H1N1. Can be used in indirect ELISA and Western Blot for the serotyping of Influenza virus type B.
