GenScript Streptavidin Magbeads; 2mL (0.5 mL Settled Beads)

Intended Use
GenScript StreptavidinMagBeads are ideal for fast and convenient purification of biotinylatedproteins, peptides, antibodies and oligonucleotides, and protein interactionstudies.

Principle
Add the sample containingbiotinylated molecules to the Streptavidin MagBeads and allow the moleculesbind to the MagBeads during a short incubation. Then separate the molecule‐bound beads with a magnetic separation rack. With indirect capture, mixthe biotinylated molecule with the sample to capture the molecule‐target complex before adding the MagBeads.

Description of Material
GenScript Streptavidin MagBeadsare super paramagnetic beads of approximately 45-100μm in diameter, covalently coated with highlypurified streptavidin. These magnetic beads are composed of magnetite coreencapsulated by agarose. The magnetic beads have streptavidin as its surfaceprotein which is 53kDa. in size having four binding site per molecule. Thesebeads have pH stability of 2 to 14 (short term); 3 to 13 (long term). The beadsare supplied as 25% slurry in phosphate buffered saline (PBS), pH 7.4,containing 20% ethanol.

Storage and Stability
This product is stableuntil the expiration date stated on the COA, when stored unopened at 2–8°C. Do NOT freeze the product. Keepthe MagBeads in liquid suspension during storage and all handling steps. Dryingwill cause loss of binding capacity and result in reduced performance.Resuspend the beads well before use. Be careful to avoid bacterial/fungalcontamination.
