Streptavidin Coated Magnetic Beads, 500 nm Diameter

500 nm diameter magnetic beads with Streptavdin protein functionalized surface.

Features

• High binding capacity of Biotin-conjugated molecules:
  • 2,000 to 4,000 pmole of biotin / mg of magnetic beads
  • 15-20 µg botinylated antibody / mg of magnetic beads
• Rapid and efficient biomolecule purification from complex samples.
• Fast response to a magnet.
• High monodispersity.
• Stable in high salt ­­conditions.

Applications

• Magnetic separation of Biotinylated cells, DNA, proteins, antibodies, and small ligands from complex samples. The streptavidin-coated magnetic beads are simply added to Biotinylated molecules for binding. The samples are transferred into a magnetic rack for easy removal of unbound residue.
