Influenza B virus (Austria/1359417/2021) NP (B/Victoria lineage) Protein, His Tag

Influenza, commonly known as ‘the flu’, is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses.Influenza viral nucleoprotein (NP) is highly conserved and the most abundant non-enzymatic viral protein in infected cells. NP is a key component of the viral ribonucleoproteins (vRNPs) complex, and its recognized functions include, but are not limited to, binding to RNA and oligomerizing for the vRNP complex, undergoing intracellular trafficking, and participating in the switch from mRNA transcription to vRNA replication.

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 63.4 kDa. The protein migrates as 80-95 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

-20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
