An enzymatic method for inosine 5′-monophosphate in the femtomole range

Assessment of capillary anion exchange ion chromatography tandem mass spectrometry for the quantitative profiling of the phosphometabolome and organic acids in biological extracts

“…Traditionally, laborious enzymatic assays [5][6][7][8][9] and HPLC-ultraviolet light detection [10] have been used to determine the concentrations of one or several analytes. However, mass spectrometric (MS) detection offers superior selectivity and the simultaneous profiling of tens of metabolites.…”
