Characterization of proteins fractionated by 2D-PAGE, stained with Pro-Q Diamond phosphoprotein stain and identified by Image Quant v5.2 software analysis as being hyper-phosphorylated in SDL and then identified by Mass Spectrometry. From the 9 spots picked, 9 different proteins were identified by MS. A full list of all the peptides identified for each spot is given in Table S6.
