Product ion analysis of oxidized cardiolipin molecular species in lipid extracts of mouse myocardium with a QqTOF-type mass spectrometer in the negative ion mode. Product ion analysis of m/z 731.477 was performed as described in the legend to Fig. 11. The ion peak at m/z 295.248 indicates the presence of an oxidized fatty acyl chain of C18:2 in the cardiolipin molecular species.
