Product specifications

Intended use

This monoclonal antibody enables specific detection of the influenza B nucleoprotein (NP) in FociSpot immunostaining of virus infected cells. The antibody can also be used in ELISA.

Serum/Plasma samples

Applications
FociSpot immunostaining of influenza B nucleoprotein in focus forming assays. Antibody functionality in FociSpot was confirmed using influenza B infected MDCK cells.

Functionality in ELISA was confirmed using recombinant protein.

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)
