Figure 3From: Optimal precursor ion selection for LC-MALDI MS/MSWorkflow of iterative precursor ion selection. Starting from an LC-MS map, the iterative precursor ion selection creates a feature-based LP and solves it. This way, a set of precursors is selected for which MS/MS acquisition is triggered. After a database search new protein hits are inserted into the LP formulation and all LP variables are updated. Afterwards, the LP is solved again, leading to a new set of selected precursors.Back to article page
