Non-Reactive Undecagold

UNDECAGOLD (UG) is a cluster complex containing 11 gold atoms, prepared using a process that gives precise control over its
surface properties. UNDECAGOLD particles are a uniform 0.8 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.
