Human EGFRvIII-coupled Magnetic Beads

The Human EGFRvIII-coupled Magnetic Beads is produced by coupling biotinylated EGFRvIII protein to streptavidin-conjugated magnetic beads. Because Streptavidin (SA) has an extraordinarily high affinity for biotin with a dissociation constant (Kd) on the order of 10-14 mol/L, the biotinylated protein can bind to the SA beads irreversibly. The pre-coupled beads are ready to use for capturing anti-EGFRvIII antibody from your sample with high specificity.

This product is intended for immunocapture, biopanning. This is a non-sterile product.

* The Isotype control (Cat. No. SMB-B01) is sold separately.

See Certificate of Analysis (CoA) for detailed instruction.

Upon receipt, please store the beads at -20°C. The shelf life is 6 months at -20 °C.

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.

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.
