Negatively charged 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.1 Each molecule of NEGATIVELY CHARGED NANOGOLD® bears multiple carboxylic acid groups; these may ionize and assume a negative charge, and these particles may therefore be used to label specific regions of cells or biomolecules with an overall positive charge. They may also be used for the attachment of labels, via cross-linking protocols.2

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