  • Streptavidin Magnetic Beads


    Streptavidin Magnetic Beads are 1 µm superparamagnetic particles covalently coupled to a highly pure form of streptavidin. Captured substrates can be useful as ligands in subsequent experiments including mRNA isolation and the capture of primary or secondary antibodies.
