Structural Analysis of Cu Binding Site in (Cu(I)·d(CpG)·d(CpG)2H) 1 Complex

complex ionwas formed using the ESI-MS method. The experimentalMS and MS/MS data of the fragmentation pattern analysiswere obtained using a Thermo Finnigan LTQ mass spectro-meter (Thermo Electron Corporation, San Jose, CA, USA).LTQ Mass Spectrometer Conditions. All spectra wereacquired in the negative ion mode over a range of m/z 250-2000 by averaging 60 scans. The heated capillary temperaturewas set at 200
