Dextran Size: 40 kDa Volume (@ 5 mg/mL Fe): 1 mL General Information: Biotin functionalized Dextran coated crosslinked iron oxide nanoparticles (CLIO-BIOT) have 1-3 superparamagnetic Fe3O4 iron oxide cores (8-10 nm in diameter) imbedded within the matrix of dextran strands of 40 or 70 kDa in size. Dextran strands are crosslinked to prevent their disassociation, ensuring long-term stability. Biotin is covalently conjugated to the nanoparticle surface. Features: Highly magnetic Highly biocompatible, non-toxic Long term stable under physiological conditions 40 kDa and 70 kDa dextran coats are available Easy loading of biomolecules through Streptavidin-Biotin interaction Applications: In vitro and in vivo magnetic labels for cells and tissues Magnetic cell separation Probes for MRI Specifications: Iron Oxide Core Diameter: 8 – 10 nm Hydrodynamic Diameter: 60 – 80 nm Polydispersity Index (PDI): < 0.25 Magnetization: 5 – 30 emu/g (room temperature) Shelf life: > 1 year (4°C storage) Supplied as liquid suspension in water
