Protein Length
Full Length
Tag Info
N-terminal 10xHis-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
Intact influenza B virus nucleoprotein (NP) cDNA (1-560aa) with an N-terminal 10xHis-tag was expressed in the Baculovirus cells. The forming protein is the recombinant full-length influenza B virus NP protein. The purity of this protein is greater than 85% determined by SDS-PAGE. Under reducing conditions, the gel showed a molecular weight band of about 65 kDa. In-stock influenza B virus NP proteins are offered now. In addition to producing specific antibodies, this recombinant influenza B virus NP protein may be used in the studies of microbiology.
Nucleoprotein (NP) is the predominant component of the influenza virus ribonucleoprotein. It is highly conserved among each type of influenza viruses. Alice Labaronne etc. demonstrated that the NP of influenza B virus has a long N-terminal tail of 70 residues with intrinsic flexibility. This tail contains the Nuclear Location Signal (NLS). And NP is imported into the nucleus by the importin-α/β pathway via direct interaction with importin-α isoforms. In addition, NP is the potential target for a universal influenza vaccine.
