is a fundamental laboratory technique used to separate macromolecules—specifically DNA, RNA, and proteins—based on their size and electrical charge . By applying an electric field to a buffered medium, scientists can "sort" complex biological mixtures into distinct bands, making it an indispensable tool in genetics, forensics, and clinical diagnostics. How It Works
Though the concept is simple—using electricity to push molecules through a "filter"—electrophoresis is one of the most powerful techniques in modern science. It transformed biology from a descriptive field into a precise, molecular discipline, providing the visual evidence needed to map the human genome and solve complex medical mysteries. Electrophoresis
Researchers use it to isolate specific genes for cloning or to study mutations. Conclusion is a fundamental laboratory technique used to separate
Small molecules move through the pores of the gel quickly, while larger molecules get tangled in the matrix and move more slowly. Over time, the molecules separate into distinct bands based on their molecular weight. Common Types It transformed biology from a descriptive field into
