Streptavidin Magnetic Beads
Introduction: Our Streptavidin-bound Magnetic Agarose Beads are useful for immunoprecipitation/pull down assay of biotin tagged proteins or nucleic acids.
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.
*BBL also sells Magnetic Bead Stand
