Upon receipt, please store the Beads at -20℃. The shelf life is 1 year at -20 ℃.
Please avoid more than 3 freeze-thaw cycles. Immediate use after reconstitution is highly recommended.
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.
Immobilized 36 μg RBD protein (Cat. No. SPD-C82E7) /1mg beads can bind (Cat. No. AC2-H5257) with an EC50 of 1.606 μg/mL (QC tested).
