Fig. 4. DIA data analysis with DeepPhospho predicted libraries in a phosphosignaling study.

Fig. 4

a Design of six spectral libraries as defined in Fig. 3b for the RPE1 DIA data analysis (left) and experimental design of the EGF signaling study in the context of MEK inhibition (right). b Number of phosphopeptides and phosphosites that were quantified from the initial search using each library. c Procedure of building a focused library to be used for an iterative search. d Number of phosphopeptides and phosphosites that were quantified from the iterative search using each library. Percentage of the total quantifiable phosphopeptide or phosphosite number is shown for each predicted library relative to Lib 1. The proportions of shared identifications (IDs), gained IDs, lost IDs, and gap IDs yielded by Lib 2 to Lib 7 compared to Lib 1 are indicated in different color.
