DESCRIPTION
Each dye-doped silica nanoparticle (DDSNP) contains thousands of ROX dye molecules. Compared to a single dye molecule, a nanoparticle achieves over 300-fold fluorescence intensity. Unlike alternative particles, the DDSNP withstands photo-bleaching, is water-soluble and does not have troublesome “blinking.” Exclusive technology allows covalent coupling of biomolecules to a ROX nanoparticle, permitting development of sensitive analyte detection systems.
STORAGE: 4ºC - Gently sonicate before use.
