MagReSyn® Streptavidin
High capacity for capture of biotinylated molecules
MagReSyn® Streptavidin microparticles contain covalently coupled streptavidin. The porous nature of the polymer technology allows for exceptional streptavidin capacity, translating into increased capacity for the immobilization/capture of biotinylated biomolecules. The high streptavidin load allows the use of as little as 10 µl beads, improving experimental miniaturization for high-throughput automated analysis. Molecular applications of MagReSyn® Streptavidin microparticles include, protein immobilization and purification; nucleic acid capture assays and preparation of single-stranded DNA templates for e.g. SELEX and pyrosequencing. The immobilization of biotinylated antibodies may subsequently be used in e.g. immunoassay.
