Structure of 0.8 nm Nanogold® gold nanoparticle (undecagold) showing the [Au11] core, coordinated ligands and peripheral reactive group (maleimide).

Mono-Sulfo-NHS-Nanogold® 0.8 nm

Precisely label amines! Nanogold® labels bind covalently, with easy enhancement.

Left: Silver-enhanced Nanogold®-labeled K+ channel Kv2.1 subunit in rat brain, X15,000 (J.-H. Tao-Cheng, NIH). Right: Darkfield STEM micrographs of Maleimido Nanogold® labeled A β peptide targeting proteasomes; sample was stained with methylamine vanadate. White dots are 1.4 nm Nanogold®. From Gregori, L., Hainfeld, J.F., Simon, M.N., and Goldgaber, D. (1997). Binding of amyloid beta protein to the 20S proteasome. J. Biol. Chem. 272, 58-62.
