SARS-CoV-2 Spike S1-coupled Magnetic Beads

It's been reported that coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Upon receipt, please store the lyophilized beads at -20°C for long term storage. The shelf life is 1 year at -20°C in lyophilized form. Please avoid more than 3 freeze-thaw cycles once reconstitution, immediate use after reconstitution is highly recommended.

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.
