  • Restrictions
    For Research Use only
  • Format
    Lyophilized
    Reconstitution
    Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
    Buffer
    Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
    Storage
    4 °C,-80 °C
    Storage Comment
    Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
    Expiry Date
    12 months

    Abstract
    SARS-CoV-2 Spike Products
    Synonyms
    E2 Protein, E2 glycoprotein precursor Protein, Surface Glycoprotein Protein, S Protein
    Background
    S protein, Spike glycoprotein, S glycoprotein, COVID-19,The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
    Molecular Weight
    136.6 kDa. Due to glycosylation, the protein migrates to 175-230 kDa based on Tris-Bis PAGE result.
