Positively charged Nanogold (2022-30NMOL)

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 POSITIVELY CHARGED NANOGOLD® bears several primary amine groups; these may ionize and assume a positive charge, and these particles may therefore be used to label specific regions of cells or biomolecules with a net negative charge. POSITIVELY CHARGED NANOGOLD® has been used as a marker to study the yest endocytic pathway.1 They may also be used for the attachment of labels, via usual cross-linking protocols.

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