  • Title: The latest advancements in proteomic two-dimensional gel electrophoresis analysis applied to biological samples.
    Author: Santucci L, Bruschi M, Ghiggeri GM, Candiano G.
    Journal: Methods Mol Biol; 2015; 1243():103-25. PubMed ID: 25384742.
    Abstract:
    Two-dimensional gel electrophoresis (2DE) is one of the fundamental approaches in proteomics for the separation and visualization of complex protein mixtures. Proteins can be analyzed by 2DE using isoelectric focusing (IEF) in the first dimension, combined to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) in the second dimension, gel staining (silver and Coomassie), image analysis, and 2DE gel database. High-resolution 2DE can resolve up to 5,000 different proteins simultaneously (∼2,000 proteins routinely), and detect and quantify <1 ng of protein per spot. Here, we describe the latest developments for a more complete analysis of biological fluids.
