Examination of Various Metal Ion Sources for Reducing Nonspecific Zinc finger−Zn2+ Complex Formation in ESI Mass Spectrometry

The formation of zinc finger peptide−Zn2+ complexes in electrospray ionization mass spectrometry (ESI-MS) was examined using three different metal ion sources: ZnCl2, Zn(CH3COO)2, and Zn(OOC(CHOH)2COO). For the four zinc finger peptides (Sp1-1, Sp1-3, CF2II-4, and CF2II-6) that bind only a single Zn...
