Product Description MagVigen™-Streptavidin magnetic nanoparticles can universally bind to any biotinylated biomolecules (ex. antibody, protein, peptide) through high affinity interaction between streptavidin and biotin. The MagVigen™-Streptavidin-biotin-biomolecule complex can be easily separated from unbound biotin-biomolecule using a magnetic rack (Cat#A20006). This provides a quick and neat way to tag biomolecules with magnetic nanoparticles. The purified nanoparticle-biomolecule complex can be used in a variety of downstream bio-separation processes (ex. protein purification, immunoprecipitation, cell isolation or depletion, and molecular detection.)Advantages of MagVigen™ – Streptavidin for Molecular enrichment• Easy and quick to make nanoparticle-primary antibody conjugates• Consistent, high quality results• High binding capacity, 25 µg biotin-antibody per mg of nanoparticles• High biocompatibility• Low non-specific binding Product Contents MagVigen™- Streptavidin (Cat# 21005P) are provided in phosphate buffered saline (PBS) containing 0.05% NaN3, 0.1% BSA. pH 7.4. Each vial contains 1 ml of solution with particle concentration of 2 mg/ml, which is enough for binding 50 µg of biotin-antibody. 1X Wash Buffer: 4 ml Nanoparticle size: about 200-500 nm measured using Dynamic Light Scattering.Polydispersity index: about 0.2.
