Invitrogen™ Streptavidin Agarose

Invitrogen™ Streptavidin Agarose

Streptavidin Agarose is suitable for isolating biotinylated molecules and complexes with biotinylated components, including antibodies, antibody-antigen complexes, ligands and receptors, nucleic acids, and nucleic acid-protein complexes. It is especially useful as an immunoprecipitation reagent for antibodies that do not bind well to protein A. The matrix consists of streptavidin covalently attached to cross-linked 4% agarose beads through a 15-atom spacer arm. Streptavidin Agarose can bind 3 to 8 mg of biotinylated IgG/ml of gel.
