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

Description: Influenza B virus (IBV) strain B/Singapore/222/79 full-length (560 a.a.) recombinant Nucleoprotein (UniProtKB/Swiss-Prot sequence accession number: P04666). 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: >90% as determined by SDS-PAGE.


SDS-PAGE analysis showing IBV-rNP product 14-IBS-S10L at approximately 62 kDa (2 μg/lane).

Applications (tested): ELISA and other immunoassays (moderate reactivity), Western blot, SDS-PAGE.
