Fig. 1From: Random and independent sampling of endogenous tryptic peptides from normal human EDTA plasma by liquid chromatography micro electrospray ionization and tandem mass spectrometryThe stability of EDTA plasma as demonstrated by electrophoresis and staining with Coomassie Brilliant Blue. EDTA Plasma samples were diluted 1:1 with 2 × tris sample buffer for tricine SDS-PAGE and 4 µL loaded per lane (~ 100 µg). Molecular markers 250, 150, 100, 75, 50, 37, 25, 15 kDa. The tricine SDS-PAGE gel shown is representative of four technical replicatesBack to article page
