Intended Use

The Influenza B Nucleoprotein ELISA Kit is an enzyme immunoassay developed for detection and quantitation of the Influenza B nucleoprotein. The ELISA antibodies only recognize the nucleoprotein from Influenza B, will not react with the nucleoprotein from Influenza A nor Influenza C. The kit has a detection sensitivity limit of 313 pg /mL Influenza B nucleoprotein. Each kit provides sufficient reagents to perform up to 96 assays including standard curve and Influenza B lysate samples.

General Description

The influenza virus is an enveloped virus that can be divided into three classes, A, B, and C, largely based upon conserved antigenic differences in the internal nucleoprotein (NP). Only Influenza A and B are clinically relevant for humans.
The primary function of NP is to encapsidate the segmented RNA and bind with the three polymerase subunits, PA, PB1 and PB2, to form ribonucleoprotein particles (RNPs) for RNA transcription, replication and packaging.
