Clinical Significance

Influenza viruses that can infect humans are divided into three types: Influenza A virus (Influenza A virus), also known as Influenza A virus. Influenza B virus (Influenza B virus), also known as Influenza B virus. Influenza C virus (Influenza C virus), also known as Influenza C virus. Influenza C virus, also known as influenza C virus. Influenza A virus is prone to antigenic mutation and has caused many worldwide pandemics.

Influenza viruses are segmented single-stranded negative-stranded RNA viruses, and the protein bound to the nucleic acid is the nucleoprotein (NP), which is antigenically stable and type-specific. Outside the viral core is a matrix protein (M protein) that is tightly bound to the viral envelope, and the outermost is the viral envelope, which has two types of spines, one for Hemagglutinin (HA) and one for Neuraminidase (NA), both of which are susceptible to mutation.   Heavy Chain Biologics presents influenza A virus and influenza B virus NP protein controls expressed through eukaryotic expression. It is suitable for use in kits for diagnosing influenza virus NP protein.
