Molecule Mass
The recombinant Influenza A virus (A/Ann Arbor/6/1960(H2N2)) nucleoprotein comprises 508 amino acids and has a predicted molecular mass of 57 kDa. It migrates as an approximately 52 kDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 8.0, 20% gly, 1mM DTT
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Nucleocapsid / NP Background Information

Influenza A viral nucleoprotein (NP) plays a critical role in virus replication and host adaptation.The influenza A virus nucleoprotein (NP) is an essential multifunctional protein that encapsidates the viral genome and functions as an adapter between the virus and the host cell machinery. NPs from all strains of influenza A viruses contain two nuclear localization signals (NLSs): a well-studied monopartite NLS1 and a less-characterized NLS2, thought to be bipartite.
