Fig. 3From: Accurate and efficient amino acid analysis for protein quantification using hydrophilic interaction chromatography coupled tandem mass spectrometryQuantitative comparison of amino acids using AccQ-Tag and HILIC-MS/MS. Individual amino acids concentrations (y-axis) as a function of hydrolysis technique and the number of residues present in BSA. The trendline represents the expected amounts of individual amino acids for protein recovered. Values that are above the trendline represent overestimation and below trendline represents underestimation of specific amino acidsBack to article page
