Probing DNA selectivity of ruthenium metallointercalators using ESI mass spectrometryElectronic supplementary information (ESI) available: table of mass spectral assignments. See http://www.rsc.org/suppdata/cc/b2/b212132h/

ESI mass spectra show that up to five ruthenium molecules can bind non-covalently to double stranded 16mer DNA, and provide information on the relative affin...
