Protein-stained SDS-PAGE shows protein complexity of samples analyzed by mass spectrometry. Representative gels analyzing calmodulin eluates of pooled glycerol gradient fractions (listed above each lane) for KREPB4 wild type (left panel, SYPRO Ruby staining), KREPB4 C51A/C54A (middle panel, silver staining), and KREPB5 wild type (right panel, silver staining). Sizes (in kiloDaltons) corresponding to molecular-weight markers are shown to the left of each panel.
