Used for the purification of biotin containing proteins or DNA binding proteins

Streptavidin iron oxide particles are used in protein chromatography, affinity chromatography, and recombinant protein expression and analysis. Streptavidin iron oxide particles have been used to study imaging of cellular spread on a three-dimensional scaffold by means of a novel cell-labeling technique for high-resolution computed tomography. Streptavidin iron oxide particles have also been used to study in vitro biomedical applications of functionalized iron oxide nanoparticles.
