The cornerstone of successful experiments is sample preparation. The products we distribute and develop are thoroughly tested and evaluated to ensure simple, efficient and reproducible sample preparation procedure.

MagResyn Streptavidin

High capacity for capture of biotinylated molecules

MagReSyn® Streptavidin microspheres 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 microspheres 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.
