• 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.
• Storage: Upon receipt, please store the Beads at -20°C for 1 year in lyophilized state.
