Basic workflow of quantitative targeted absolute proteomics (QTAP). Blue boxes (steps 2 to 5) correspond to section “Method Setup for QTAP”. The green box (step 6) corresponds to section “Preparation of protein samples”. The red boxes (steps 7 to 9) correspond to section “Absolute quantification by LC-MS/MS”. AAA, amino acid analysis.
