200nm Reactant Free Gold Nanoparticles

  Composition: Citrate stabilized gold colloidCore Size: 200nmParticles per ml: 1.91E+9   Purity: >99% reactant free Formulation: Supplied in 0.1mM phosphate buffered saline (PBS) Intended use: Our extensively purified reactant free gold nanoparticles are ideal for sensitive applications requiring a minimum amount of contaminating reactants remnant from the manufacturing process. This product is well suited for conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can be used in blotting, electron microscopy and immunohistochemistry applications. Properties Cytodiagnostics reactant free gold nanoparticles are made using a unique proprietary protocol resulting in pure, reactant free particles with superior size distribution and shape compared to that of the leading competitor.  Our gold nanoparticle preparations have a narrow size distribution (CV of less than 15%), exceptional protein adsorption properties
