Polyacrylamide Gel Electrophoresis (PAGE) is a laboratory technique used to separate proteins or nucleic acids based on their size and charge. It involves the use of a polyacrylamide gel matrix, which provides high-resolution separation due to its fine pore structure. The molecules move through the gel under an applied electric field, allowing researchers to analyze protein composition, purity, and molecular weight.
