Human influenza B IgM ELISA kit is designed for determining in-vitro quantitative amounts of human IgM antibodies against influenza B in serum or plasma samples. This assay has a minimum analytical sensitivity limit of 1.19 U/ml.
Influenza B viruses can be divided into two co-circulating lineages (B/Yamagata/16/88-like or B/Victoria/2/87-like viruses), this is based on their antigenic properties on the surface of the glycoprotein hemagglutinin. At present influenza B has only been found to cause human or seal infections. The influenza B virus capsid is filamentous and spherical, consisting of more than 500 surface projections of neuraminidase and hemagglutinin. The genome of the virus is around 14548 nucleotides in length and consists of eight linear negative-sense, single stranded RNA.
The minimum detection sensitivity level of IgM antibodies to influenza B using current human influenza B IgM ELISA kit was 1.19 U/ml. The dynamic range for this assay is 1.0 – 250.0 U/ml.
