+**2DE** is a powerful analytical method primarily used for [Protein Separation](/wiki/protein_separation). It resolves complex mixtures of [Proteins](/wiki/protein) by separating them in two dimensions, first by charge and then by mass. This technique allows for the visualization and identification of thousands of proteins within a single sample, crucial for studying changes in protein expression.
