Moderately pure Influenza B Virus, strain Lee, recombinant nucleoprotein (IBV-rNP) from S. cerevisiae, lyophilized

Description: Influenza B virus (IBV) strain B/Lee/1940 full-length (560 a.a.) recombinant Nucleoprotein (UniProtKB/Swiss-Prot sequence accession number: P04665). Expressed in S. cerevisiae and purified from yeast lysates by combination of chromatographic techniques and ultracentrifugation in CsCl gradients under native (non-denaturing) conditions.

Form: Lyophilized in PBS with 3 mg/ml sucrose.

Storage: Shipped at ambient temperature (shipment costs: 65 € to Europe and 100 € to US). Lyophilized products may be stored at 2-8°C or at -20°C for longer periods.

Reconstitution: add 100 μl of deionized water for reconstitution of 100 µg of IBV-rNP in each separate vial. Check lyophilized material to be completely dissolved before use.

Concentration of reconstituted product: 1.0 mg/ml in PBS.

Purity: >70% as determined by SDS-PAGE.
