High Capacity Streptavidin Functionalized Magnetic Nanoparticles

Streptavidin SilaMag Nanoparticles (a.k.a. "Streptavidin SilaMag NanoBeads")are streptavidin functionalized magnetic nanoparticles with an average size of 400 nm.

Streptavidin SilaMag Nanoparticles are made according to a modified Stoeber process by hydrolysis of orthosilicates and consecutive coupling with streptavidin. Biotin binding activity of the immobilized streptavidin is optimally preserved through a proprietary functionalization procedure.

Streptavidin SilaMag Nanoparticles are used for fast and specific binding, and separation of biotinylated molecules (proteins, antibodies, nucleic acids, and small ligands).

Features:

• High binding capacity (>1000 pmole of free biotin per mg of particles)
• Low non-specific binding to proteins and nucleic acid
• Fast magnetic separation

Applications:

• Affinity purification(s) of biotinylated substances
• Isolation and binding of biotin-tagged recombinant proteins
• Purification of antigens with biotinylated antibodies
• Solid phase binding assays with biotinylated substrates and ligands
• Cell separation and assay development
