Reproducibility of the sequential depletion method. Technical (A) and biological (B) replicates were analyzed by MALDI-TOF/TOF MS in order to evaluate the reproducibility. Coloured squares show the identification of each protein on the different replicates. (C) SDS-PAGE gel (10% acrylamide, silver staining), illustrating the representative protein profiles obtained after the sequential depletion of three independent sera by duplicate, which further demonstrate the reproducibility of the strategy.
