Polyacrylamide Gel Electrophoresis

Polyacrylamide Gel Electrophoresis (PAGE) is a common technique used in biochemistry and molecular biology to separate and analyze molecules in a mixture based on their size. It works by using an electric charge to move molecules through a polyacrylamide gel, where molecules of different sizes move at different rates. By examining the separated molecules, scientists can learn valuable information such as their size, shape, and identity. PAGE is used to separate proteins, DNA, and RNA, and can also be used to study their structures and interactions. This method is useful for a variety of applications, including analyzing gene expression, identifying mutations, and determining the structure of biological macromolecules.
