Identifications of PTM peptides/sites from global DIA-MS runs. a The numbers of identified PTM peptides/sites from 100 cells via the spectral libraries constructed from PTM-enriched DIA data of PDX samples. b Evaluation of phosphopeptide spectral library size towards phosphorylation site identification from the spectral libraries built using phopshopeptide-enriched from ccRCC samples
