• Background: The SARS-CoV-2 (Omicron) Spike RBD-coupled Magnetic Beads is produced by coupling biotinylated SARS-CoV-2 spike RBD to streptavidin-conjugated magnetic beads. The spike RBD coupled to the beads contains the critical mutations identified in the SARS-CoV-2 Omicron variants (BA.1). The pre-coupled beads are ready to use for capturing anti-SARS-CoV-2 antibody or ACE2 protein from your sample with high specificity.
• 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.
