Streptavidin Magnetic Beads

Approximately 1.5 mg/ml streptavidin is immobilized on non-cross-linked beaded magnetic agarose where iron is encapsulated by agarose. The beads have excellent magnetic properties allowing rapid and efficient capture and low non-specific binding using a Magnetic Bead Stand*. These beads are stable at pH 2-11. The product is supplied as 50% suspension of streptavidin magnetic agarose in 20% ethanol aqueous suspension when packed.
*NextGen Bioproducts also sells Magnetic Bead Stand
