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

• Streptavidin—purified recombinant streptavidin protein (53kDa, near-neutral pI); tetrameric with four biotin-binding site per molecule
• Agarose resin—support is crosslinked 6% beaded agarose (CL-6B), the most popular resin for protein affinity purification methods
• Inert and stable—streptavidin is immobilized by charge-free, leach-resistant covalent bonds, resulting in low nonspecific binding and enabling multiple uses without decline in yield
• Standard capacity—this variety of beads has a normal load of immobilized streptavidin, providing a binding capacity of 1 to 3 mg of biotinylated BSA per mL of resin

Streptavidin agarose beads have physical and chemical properties that enable them to be used in a variety of batch- or column-type affinity procedures. Biotinylated antibodies, proteins, peptides, nucleic acids and other molecules or interaction complexes can be captured, immunoprecipitated, removed or purified from samples using this streptavidin resin.
