This product is intended for immunocapture, biopanning and flow cytometry. This product is produced non sterile.

Magnetic Beads™ Streptavidin are 2 µm superparamagnetic particles covalently coupled to a highly pure form of streptavidin (SA). The beads can be used to capture biotin labeled substrates including antigens and antibodies. Biotinylated substrates bind to the beads irreversibly owning to the extraordinarily high affinity between streptavidin and biotin with a dissociation constant (Kd) on the order of 10 to 14 mol/L. High binding capacity and low non-specific binding of proteins make this bead ideally suited for protein isolation applications.

Antibody Purification:
1. Reconstitute the beads with ultrapure water to 1 mg/mL, and wash the beads for three times.
2. Dilute the biotinalyted protein or antibodies with Assay Buffer and add to the beads. Incubate for 60 minutes at room temperature in a rotary mixer.
3. Wash the beads for four times, and add Assay Buffer to the beads. The beads are ready to use for the next experiment.
