Recombinant SARS-CoV-2 ORF3b protein

  • Background:

    SARS-CoV-2 ORF3b is homologous to SARS-CoV ORF3b, although the proposed protein is much shorter due to the presence of premature stop codons (Probable) . Elicits strong specific antibody response (PubMed:32807944) .
  • Abbreviation:

    ORF3b
  • Synonyms:

    ORF3b; ORF3b protein
  • UniProt:

    P0DTF1
  • Accession Number:

    P0DTF1
  • Expression System:

    E. coli
  • Tag:

    N-SUMO & C-His
  • Sequence:

    Met1-Val22
  • Endotoxin:

    < 10 EU/mg of the protein as determined by the LAL method.
  • Purity:

    > 90% as determined by reducing SDS-PAGE.
  • Bioactivity:

    Not validated for activity
  • Reconstitution:

    It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
  • Shipping Conditions:

    This product is provided as lyophilized powder which is shipped with ice packs.
  • Storage Conditions:

    Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
  • Calculated Molecular Weight:

    18.2 kDa
  • Formulation:

    Lyophilized from a 0.2 µm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
    Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
    Please refer to the specific buffer information in the printed manual.
  • Species:

    SARS-CoV-2
