Streptavidin Agarose

Recombinant Streptavidin purified from E.coli is covalently bound to 6% cross-linked agarose bead. The Streptavidin-linked resin which is stable at pH 2-11 can be used to separate biotinylated products from non-biotinylated products. Biotinylated molecules can be RNA, DNA or protein which binds to the Streptavidin agarose bead with extremely high affinity. This high-affinity interaction is useful to monitor protein-RNA, protein-DNA, and protein-protein interaction.
Product Description: Approximately 1.5 mg/ml Streptavidin has been immobilized on 6% cross-linked beaded agarose. This product is supplied as 50% suspension of Streptavidin Resin in aqueous ethanol when packed.
