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 40μg S protein trimer/1mg beads can bind the Anti-S1 Antibody with an EC50 of 0.5720μg/mL (QC tested).
Accelerated stability test. After placing the lyophilized beads at 37℃ for 7 days, binding activity between the S SARS-CoV-2 Spike Trimer (P.1) Coupled Magnetic Beads (Cat.No. MBS-K031) and anti-SARS-CoV-2 Spike S1 antibody showed little deviation from the unaccelerated sample (%RSD<5%). Data were measured on day 0, 3, 7 respectively.
Freeze-thaw stability test. After different freeze-thaw cycles, binding activity between SARS-CoV-2 Spike Trimer (P.1) Coupled Magnetic Beads (Cat.No. MBS-K031) and anti-SARS-CoV-2 Spike S1 antibody showed little deviation from the unfree-thaw sample (%RSD<5%). Three freeze-thaw cycles were performed.
