High Capacity Streptavidin Functionalized Magnetic Nanoparticles

Streptavidin SilaMag Nanoparticles (Catalog # SSMP-101-1 and SSMP-101-2) 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).

 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.

 Features:

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

Catalog # SSMP-101-1 and SSMP-101-2

Streptavidin SilaMag Nanoparticles are supplied at a concentration of 1 mg/mL in a storage buffer of 1X PBS, 0.05% NaN₃, 0.05% Tween 20, 0.1% BSA, pH 7.4.

Precautions and Disclaimer

Streptavidin SilaMag Nanoparticles are for laboratory use only. The storage buffer contains 0.05% sodium azide which is toxic. Please refer to the Safety Data Sheet (SDS).

Storage/Stability

The suspension should be stable approximately three months stored at 2-8 °C. DO NOT FREEZE. Freezing will damage bead structure.
