Dextran Size: 70 kDa Volume (@ 5 mg/mL Fe): 5 mL General Information: Amine-functionalized Dextran coated crosslinked iron oxide nanoparticles (CLIO-NH2) have 1-3 superparamagnetic Fe3O4 iron oxide cores (8-10 nm in diameter) imbedded within the matrix of dextran sugar strands of 40 kDa or 70 kDa size. Dextran strands are crosslinked to prevent their disassociation, ensuring long-term biological stability. Dextran surface has been functionalized with Amine NH2 groups. Features: Highly biocompatible, non-toxic Long term stable under physiological conditions 40 kDa and 70 kDa dextran coats are available Highly magnetic Can be easily conjugated to NHS-activated ligands 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: 50 – 110 nm Polydispersity Index (PDI): < 0.3 Nanoparticle Charge: Between 1 and 10 mV Magnetization: 5 – 30 emu/g (room temperature) Shelf life: > 1 year (4°C storage) Supplied as liquid suspension in PBS
