Pierce™ Streptavidin agarose is a standard-capacity crosslinked 6% beaded agarose resin of immobilised recombinant streptavidin protein for use in a variety of biotin-binding affinity purification methods.

• 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
• Standard capacity beads with a normal load of immobilised streptavidin, providing a binding capacity of 1 to 3 mg of biotinylated BSA per ml of resin
