Dextran Size: 40 kDaFluorescent Dye Label: AFDye 555Volume (@ 5 mg/mL Fe): 2 mLGeneral InformationFluorescent, Biotin functionalized Dextran coated crosslinked iron oxide nanoparticles (CLIO-BIOTD) 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 and fluorescence dye are covalently conjugated to the nanoparticle surface.Features:SuperparamagneticFluorescently labeled (AFDye 488, AFDye 555, AFDye 647, or IR750 dye)Highly biocompatible, non-toxicLong term stable under physiological conditions40 kDa and 70 kDa dextran coats are availableEasy loading of biomolecules such as Antibodies through Streptavidin-Biotin interaction Applications:In vitro and in vivo dual magnetic and fluorescence labels for cells and tissues.Magnetic, fluorescence, or dual cell separation.Probes for MRI.
