Product Description
The SARS-CoV-2 Spike Trimer (P.1) Coupled Magnetic Beads is produced by coupling biotinylated SARS-CoV-2 spike trimer to streptavidin-conjugated magnetic beads. The spike proteins coupled to the beads contain 12 mutations (L18F, T20N, P26S, D138Y, R190S, K417T, E484K, N501Y, D614G, H655Y, T1027I, V1176F) identified in the Brazilian variant (known as P.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. This is a non-sterile product.
* The Isotype control (Cat. No. SMB-B01) is sold separately.
Reconstitution
See Certificate of Analysis (CoA) for detailed instruction.
Storage
Upon receipt, please store the Beads at -20°C. The shelf life is 1 year at -20 °C.
Please avoid more than 3 freeze-thaw cycles once reconstitution, immediate use after reconstitution is highly recommended.
Assay Principles
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.The magnetic beads technology makes use of the easy and efficient collection of beads in magnetic field to facilitate antibody purification in a simple workflow of “bind-wash-elute”. In contrast to common separation techniques, this method does not require columns or centrifugation, and is therefore ideal in high-throughput applications.

Performance Data
Typical Data

Immobilized 40 μg SARS-CoV-2 S protein trimer to 1mg Beads can bind the ACE2 with an EC50 of 0.14μg/mL (QC tested).
Protocol
Accelerated stability test. After placing the lyophilized beads at 37°C 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.
Protocol
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.
