Product specifications

Intended use

This kit is intended for FociSpot immunostaining of the influenza B nucleoprotein, which enables enumeration of influenza B virus foci in focus forming assays (FFA). For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

FociSpot
In FociSpot, virus foci are detected by using mAbs specific to viral proteins. After fixation and permeabilization of infected cells in a 96-well plate, the virus-specific biotinylated detection mAb is added. The use of Streptavidin-ALP enzyme conjugate, followed by a precipitating substrate enables detection of foci. Foci can be counted manually, but counting with Mabtech IRIS 2 is rapid and offers easy data handling.

FociSpot immunostaining of influenza B nucleoprotein in infected MDCK cells. MDCK cells were infected with influenza B virus (titrated, virus dilutions16,000x, 32,000x, and 64,000x are shown). After fixation and permeabilization, foci were detected using anti-influenza B (NP) mAb 4D5, followed by Streptavidin-ALP and BCIP/NBT-plus substrate. Foci were counted using the Apex software in Mabtech IRIS 2.

Influenza B (NP)

Analyte description

The Nucleoprotein (NP) is a structural protein and encapsidates the negative strand RNA of influenza B into ribonucleoproteins (RNP). NP plays a role in replication, transcription, RNA packaging, and nuclear trafficking. The NP does not only interact with the RNA, but also the viral polymerase, the M protein, and several host factors. 

Alternative namesNucleoprotein, NP (of influenza B)
