SARS-CoV-2 Spike NTD-coupled Magnetic Beads

The SARS-CoV-2 Spike NTD-coupled Magnetic Beads is produced by coupling biotinylated SARS-CoV-2 spike NTD protein to streptavidin-conjugated magnetic beads. Because Streptavidin (SA) has an extraordinarily high affinity for biotin with a dissociation constant (Kd) on the order of 10-14 mol/L, the biotinylated protein can bind to the SA beads irreversibly. The pre-coupled beads are ready to use for capturing anti-SARS-CoV-2 antibody or ACE2 protein from your sample with high specificity.
