Properties 

Cytodiagnostics PEGylated Gold Nanoparticles with carboxyl functional groups are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to the leading competitor (Tech Note #104) and are ideal for development of covalent gold nanoparticle conjugates. 

The carboxyl functionalized gold surface allows for covalent conjugation of antibodies, proteins and other ligands using standard EDC/NHS coupling chemistry.   

These gold nanoparticles have a narrow size distribution (CV of less than 15%) and more than 95% spherical particles. 

Low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered.

All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.
