Streptavidin Mono Mag (1 µm) are hydrophilic, streptavidin conjugated magnetic beads with diameter of 1 µm. The monolayer of streptavidin that is covalently coupled to their surface makes most of the biotin binding sites sterically available for binding of biotinylated nucleic acids, antibodies, or other biotinylated ligands and targets. With their large surface area, uniform size, narrow size distribution and unique surface coating, Streptavidin Mono Mag (1 µm) exhibit high binding capacity and low non-specific binding.
