Two-Dimensional Electrophoresis Protocols to Analyze the Microtubule-Associated Tau Proteins from Several Biological Sources.

Technology breakthrough in proteomics enables to gather qualitative and quantitative information about a protein or a complex mixture of proteins. Two-dimensional gel electrophoresis remains an interesting technique, which provides an overview of the complexity of isovariants from a single protein when coupled to western blotting. Here, we describe a detailed protocol for the two-dimensional analysis of microtubule-associated Tau isovariants from cell to human or mouse brain tissue.
