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.

MagReSyn® Streptavidin MAX

Ultra-capacity for capture of biotinylated molecules

MagReSyn^® Streptavidin MAX microparticles have been specially engineered for custom applications where maximum binding of biotinylated molecules is required. This includes microplate applications where miniaturization and high-throughput automated analysis are required. This product primarily targeted for oligo/peptide isolation, and it is not recommended for protein isolation due to possible steric hindrance with the high streptavidin load. 

Binding capacity (DNA): > 120 000 pmoles.ml^-1 (Biotinylated oligo, 25-mer)
Bead size: ~5-10 µm
Formulation: 10 mg.ml^-1 suspension in sodium phosphate buffer

* Please note that MagReSyn^® Streptavidin MAX is a custom product with minimum 2 weeks lead time from date of order *
