Fig. 2From: Analysis of urinary exosomal metabolites identifies cardiovascular risk signatures with added value to urine analysisEvaluation of the three methodological approaches developed for the analysis of the exosomal metabolome. The three spectra corresponding to methanolic extraction (1H NMR), organic solvent extraction (1H NMR), and direct analysis of the exosomal pellet (without extraction) (1H HR-MAS) are shown overlaid. 1H HR-MAS spectrum was scaled by a factor of 0.1301 for proper visual comparison matching the noise levelBack to article page
