Abstract: Figure 2. Quantitative identification of IDPs and oxidized IDPs in mouse tissues. A, LC-ESI-MS/MS analysis of endogenous carnosine in the mouse skeletal muscle. Representative LC-ESI-MS/MS chromatograms of spiked isotope-labeled carnosine (upper trace), and endogenous carnosine (lower trace) are shown. B, LC-ESI-MS/MS analysis of endogenous 2-oxo-carnosine in the mouse skeletal muscle. Representative LC-ESI-MS/MS chromatograms of spiked isotopelabeled 2-oxo-carnosine (upper trace), and endogenous 2-oxo-carnosi…
