More Details about
NanoLink TM Streptavidin Magnetic Beads
NanoLink TM Streptavidin Magnetic Beads consists of polymer-encapsulated magnetite (super paramagnetic) beads possessing covalently cross-linked streptavidin on their surface. The product consists of a heterogeneous population of beads ranging in size from 150 to 775 nanometers.
NanoLink TM Streptavidin Magnetic Beads are particularly suited for high throughput robotic pplications where high biotin loads from biotinylated biomolecules must be immobilized using a suitably strong magnet.
