Dextran Size: 70 kDa Fluorescent Dye Label: AFDye 488 Volume (@ 5 mg/mL Fe): 0.5 mL General Information: Fluorescent dye functionalized Dextran coated crosslinked iron oxide nanoparticles (CLIO-DYE) 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. Fluorophores are covalently conjugated to the nanoparticle surface. Features: Highly magnetic Highly biocompatible, non-toxic Fluorescently labeled (AFDye 488, AFDye 555, AFDye 647, or IR750 dye) Long term stable under physiological conditions 40 kDa and 70 kDa dextran coats are available Dual-modality magnetic and fluorescence probes Applications: Dual-modality probes for MRI and Fluorescence imaging In vitro and in vivo labels for cells and tissues Dual magnetic and florescence cell separation Specifications: Iron Oxide Core Diameter: 8 – 10 nm Hydrodynamic Diameter: 60 – 80 nm Polydispersity Index (PDI): < 0.25 Nanoparticle Charge: Between -3 and -0.3 mV Magnetization: 5 – 30 emu/g (room temperature) Fluorescent dye: AFDye 488, AFDye 555, AFDye 647, or IR750 Shelf life: > 1 year (4°C storage) Supplied as liquid suspension in water
