Streptavidin Magnetic Beads are nano-superparamagnetic beads covalently coated with highly purified streptavidin. The beads can be used for the binding of biotinylated molecules, including DNA, RNA, PCR products, oligonucleotides, antibodies, peptides, and other proteins. The streptavidin-biotin interaction has very high binding affinity (Kd=10-15). With a fast magnetic response rate, high protein binding capacity and low non-specific binding, Streptavidin Magnetic Beads provide a rapid and efficient method to capture biotinylated molecules, which can be subsequently used in a wide variety of applications, including immunopurification, immunoassays, cell isolation, and organelle isolation, etc.
