  • Background
    The streptavidin magnetic beads are uniform size, narrow size distribution with large surface area and unique surface coating, it is easy to capture the biotinylated proteins or other molecules, and the bounded protein have no activity lost, can help us get the best performance and highly reproducible results.
  • Application
    This product is intended for immunocapture, biopanning and flow cytometry.
  • Reconstitution
    See Certificate of Analysis for details of reconstitution instruction and specific concentration.
  • Storage

    Upon receipt, please store the beads at -20℃ in a power state.

    Once open the bottle of beads, please use the beads immediately.

    Do not to freeze thaw the Beads after reconstitution.
  • Assay Principles
    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 Magenetic beads are pre-coupled with Streptavidin tetramer protein and blocked with BSA, it is a ready-to-use beads, which can be used for binding biotinylated proteins and antibodies.

    Application Method:

    a) Reconstitute the beads with ultrapure water to 1mg/mL, and wash the beads for three times.

    b) Dilute the biotinalytated protein or antibodies with Assay Buffer, and add to the beads, incubate for 60 minutes at room temperature in a rotary mixer.

    c) Wash the beads for four times, and add assay buffer to beads for next experiment.
