Active Recombinant COVID-19 N protein(BA.2*&BA.3*/Omicron), His-tagged

• Cat.No.: N-729V
• Product Overview: Recombinant COVID-19 N protein(BA.2*&BA.3*/Omicron)(Met 1 - Ala 419)(Accession # QHO62115.1(P13L, ERS31-33del, R203K, G204R, S413R)), fused with His tag at the C-terminus, was expressed in HEK293.

Specification

• Species: COVID-19
• Source: HEK293
• Tag: His
• ProteinLength: Met 1 - Ala 419
• Form: Lyophilized from 0.22 μm filtered solution in PBS, 0.2M Arginine, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized SARS-CoV-2 Nucleocapsid protein, His Tag (BA.2*&BA.3*/Omicron) at 1 μg/mL (100 μL/well) can bind Anti-SARS-CoV-2 Nucleocapsid Antibody, Human IgG1 with a linear range of 0.1-2 ng/mL.
• Molecular Mass: The protein has a calculated MW of 47.1 kDa. The protein migrates as 30-35 kDa and 60-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: This product is stable after storage at:
  -20°C to -70°C for 12 months in lyophilized state;
  -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
