Polystyrene particles, Superparamagnetic, Fluorescent and Streptavidin-modified (PS-MAG-Fluo-SA)

The preparation of our streptavidin-modified magneto-fluorescent particles consists of a multi-step process, including particle synthesis/iron oxide incorporation, the coating of the magnetic particles with a special polymer, the incorporation of selected fluorophores into the polymer shell that bears carboxylic groups, and finally the covalent immobilization of high-purity streptavidin on the particle surface using carbodiimide chemistry. By this strategy, multifunctional streptavidin-modified magnetic polystyrene particles with high monodispersity (CV < 5 %), excellent magnetic response, strong fluorescence, and high binding capacity for biotinylated ligands can be realized. All products are available in a range of discrete sizes from 1 Ám to 10 Ám as a 1 % w/v aqueous suspensions. They can be used in a variety of applications like cell separation, nucleic acid isolation, biomolecule purification, and particle-based immunoassays.
