10nm Stabilized Gold Nanoparticles Optical Density:1 OD 08E-08 * All concentrations as

08E-08 * All concentrations as indicated at an optical density of 1 (OD=1

The protective inert PEGylated layer of Cytodiagnostics methylated silver nanoparticles make them ideal for use in applications that requires stringent control of non-specific protein binding to the nanoparticle surface

Conjugation of the oligonucleotide is achieved by the formation of a strong and stable gold-thiol bond

Surface functionality: NHS-ester (~ 1 NHS group/nm2) (10kDa PEG-spacer between silver surface and NHS-group)
