Streptavidin Magnetic Beads

Magnetic bead peptide pulldown

Faster Magnetic Response; Simpler Protocols;

LifeTein provides a series of magnetic beads for any bioseparation application, from microliter scale to liter scale. Our Magnetic Beads are nano-superparamagnetic beads covalently coated with highly functional groups or compounds such as maleimide, primary amine, NHS (N-hydroxysuccinimide), carboxylic acid, purified streptavidin, protein A, reduced glutathione, nickel-charged nitrilotriacetic acid, and groups for DNA/RNA purification.

Streptavidin Magnetic Beads are nano-superparamagnetic beads covalently coated with highly purified streptavidin. The beads provide a rapid and efficient method to capture biotinylated molecules, including DNA, RNA, PCR products, oligonucle- otides, antibodies, peptides, and other proteins, which can be subsequently used in a wide variety of applications, including immunopurification, immunoassays, cell isolation, and organelle isolation, etc.


Product Features:

Magnetic Separation – Fast response, complete purification process within 30 min, no chromatograph, no centrifugation, maximally preserve protein activity

Excellent Suspension Ability – Nanometer scale, rapid conversion from solid-phase to solution and vice versa

High Binding Capacity – efficient coupling, higher binding surface area

Low non-specific Binding –hydrophilic microspheres, low non-specific binding

Fully compatible with automation and LC-MS/MS analyses

Product Procedures:


The beads are simply added to samples and biotinylated molecules/cells will bind to the beads. After washing unbound impurity off, the biotinylated molecules/cells can be eluted from the magnetic beads or the bound magnetic beads can be directly used in downstream experiments. The process can be completed manually or fully automated for high throughput applications.

The product is not thoroughly tested and is not intended for human use. For in-vitro and research use only.
