50nm Reactant Free Gold NanoUrchins

Composition: Citric acid stabilized Gold NanoUrchins Core Size: 50nm Absorption max: 560nm Particles per ml: 3.5E+10 Formulation: Supplied in 0.1mM phosphate buffered saline (PBS) Intended use: Our extensively purified reactant free Gold NanoUrchins 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 Gold NanoUrchins are unique spherical gold nanoparticles with spiky protrusions, which result in absorption of light in the far-red. They are made using a unique proprietary protocol resulting in pure, reactant free particles with excellent size distribution. Our Gold NanoUrchins have a narrow size distribution (CV of less than 8%) and exce
