Nanogold/Undecagold Labeling Reagents

Nanogold® is a better gold label. The 1.4 nm Nanogold® particle is a gold compound: it is not just adsorbed to proteins, like colloidal gold, but covalently reacts at specific sites under mild buffer conditions. This gives a well defined product that can be purified chromatographically. Nanogold® brings the versatility of fluorescent conjugation to gold labeling.
