title: Undecagold clusters for site-specific labeling of biological macromolecules: simplified preparation and model applications.
abstract: We report simple and rapid procedures for the synthesis of a variety of stable, water-soluble undecagold cluster, and model applications of a thiol-reactive gold cluster for the specific labeling of cysteine residues in proteins.
