Non-Reactive Nanogold

NANOGOLD® (NG) is a revolutionary new type of gold particle, prepared using a process that gives precise control over its size distribution and surface properties. NANOGOLD® particles are a uniform 1.4 nm in diameter, making them a suitable calibration standard for electron microscopy. They do not aggregate, as do colloidal gold products, nor do they possess affinity for proteins as colloidal gold particles do. This product does not posess active functionality: it cannot be linked specifically to proteins or antibodies. It is anticipated that this product will be used as a size or resolution standard for the electron microscope.
