Proteomic workflow and data quality. (A) Proteomic workflow. (B) Number of proteins quantified in at least 2 replicate comparisons within each comparison for each patient. (C) Pearson correlation coefficient for replicate comparisons (ratio values) for each patient. (D) Log2 fold-change of CD34 and CD38 protein expression comparing the “AML_engrafting vs AML_non-Engrafting #1” population. (E) PCA for indicated comparison using all quantified proteins.
