Mono-DBCO-Undecagold in 5 aliq

Undecagold (Au₁₁) is smaller than Nanogold^®, with a core of 11 gold atoms only 0.8 nm in diameter. It is ideal for ultra-high-resolution EM work such as cryo-EM, scanning transmission electron microscopy (STEM), or for resolving elements of large structures by TEM in conjunction with image processing. Undecagold has been used to see the biotin binding sites on avidin to 1 nm resolution by electron microscopy. It is prepared in a form with one reactive arm for cross-linking to a specific site on a target molecule, and is available with different reactivities for labeling different sites.

• Ultra small 0.8 nm gold core.
• Use to prepare the smallest possible gold probes.
• Highest possible resolution.
• Site specific covalent labeling with choice of reactivities.
