Pierce™ High capacity streptavidin agarose consists of purified recombinant streptavidin that has been covalently immobilised at a high density onto high-quality crosslinked 6% beaded agarose.

• Purified recombinant streptavidin protein (53 kDa, near-neutral pI); tetrameric with four biotin-binding site per molecule
• Support is crosslinked 6% beaded agarose (CL-6B), the most popular resin for protein affinity purification methods
• Streptavidin is immobilised by charge-free, leach-resistant covalent bonds, resulting in low non specific binding and enabling multiple uses without decline in yield
• High capacity beads have a dense load of immobilised streptavidin, providing a binding capacity greater than 10 mg of biotinylated BSA per ml of resin
