Streptavidin Magnetic Beads

Streptavidin Magnetic Beads are used as a rapid and simple tool for immunoprecipitation, purification and other applications. Biotinylated molecules, such as nucleic acids, peptides and proteins can bind to Streptavidin Magnetic Beads easily. By applying magnetic attraction, Beads-molecules complex will be temporarily immobilized at tube wall, so the other parts in supernatant can be removed easily and efficiently.
