  • Background
    The pre-coupled magnetic beads coupled with biotinylated SARS-CoV-2 Spike trimer(D614G) protein to streptavidin conjugated magnetic beads, which can capture the Anti- SARS-CoV-2 antibody or ACE2 protein from cell or serum sample. The beads are in uniform size, narrow size distribution with large surface area and unique surface coating, which can help you get the best performance and highly reproducible results. This very first SARS-CoV-2 Spike trimer(D614G) protein-coupled magnetic beads will bring great convenience with minimum non-specific binding and developed protocols. This ready to use products could greatly save your time and hassle.
  • Application
    This product is intended for immunocapture, biopanning and flow cytometry. This product is produced non-sterile.
  • Reconstitution
    See Certificate of Analysis (CoA) for detailed instruction.
  • Storage

    Upon receipt, please store the Beads at -20℃ for 1 year in lyophilized state.

    Please avoid more than 3 freeze-thaw cycles. Immediate use after reconstitution is highly recommended.

  • Assay Principles
    The magnetic beads technology makes use of the easy and efficient collection of beads in magnetic field to facilitate antibody purification in a simple workflow of “bind-wash-elute”. In contrast to common separation techniques, this method does not require columns or centrifugation, and is therefore ideal in high-throughput applications.

    Antibody Purification:

    1. Resuspend the lyophilized beads by adding the buffer of choice.

    2. Add analyte to the suspension, mix and incubate to enable specific binding of the beads and the target protein.

    3. Magnetize beads, remove supernatant, and wash unbound protein fractions to capture target protein-bound beads.

    4. Wash, magnetize the beads and collect purified target protein for use in downstream applications.
