Electrospray Gold Standards of Molecular Mass 32- to 52-kDa: Charging Patterns of the Ubiquitous Virus-like Clusters, I - 197Au144-5(SR)60, R = 8 Variants, in Native [HPLC]-ESI-MS
Abstract:Faradays legendary Molecules of Gold have stimulated intense interest (over 165 years) but have only recently begun to yield their secrets to modern methods of chemical analysis. Here(in), we demonstrate how striking charging patterns emerge directly from native electrospray of large, gold-rich molecules that were generated by reduction of various (8) small gold(I)thiolate complexes [-RS-Au(I)-SR-], followed by extensive thermochemical processing to enrich the most robust forms. In each case (R), electrospray … Show more
