Protein extracted from PFPE tissue is suitable for two-dimentional gel electrophoresis.

Non-malignant human duodenum tissue was divided into 3 samples and either flash-frozen in liquid nitrogen (cryo), or prepared as PFPE or FFPE tissue. Proteins from cryo and PFPE tissue were extracted in 2D buffer (30 mM Tris-HCl, pH 8.8, 7 M urea, 2 M thiourea, 4% CHAPS, 75 mM DTT) supplemented with protease inhibitor. Proteins from FFPE tissue were extracted in EXB Plus buffer supplemented with protease inhibitor, precipitated with acetone and resuspended in 2D buffer (as described in Guendisch et al. 2013). Samples (150 µg) were separated by 2-D PAGE. Data kindly provided by Karl-Friedrich Becker, Technical University of Munich, Germany.
