Negatively Charged Undecagold

UNDECAGOLD is a new type of gold label, consisting of a cluster complex of 11 gold atoms, ligated by triarylphosphines and chloride ions. Each molecule of NEGATIVELY CHARGED UNDECAGOLD bears multiple carboxylic acid groups; these may ionize and assume a negative charge. They may also be used for the attachment of labels, via established cross-linking protocols. 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.

NEGATIVELY CHARGED UNDECAGOLD particles should be frozen upon receipt, and stored at -20°C.
