Electrophoresis Explained: Principles and Applications

Electrophoresis uses electrical currents to separate DNA, RNA, proteins and carbohydrates based on their charge and size. Since its discovery over 200 years ago, this technique has evolved into an essential tool across molecular biology, forensics, clinical diagnostics and pharmaceutical research. While gel electrophoresis, capillary electrophoresis and isoelectric focusing each offer distinct advantages for different applications, challenges such as resolution requirements and throughput needs influence method selection.

This infographic explores the fundamental principles of these three major electrophoresis techniques while showcasing their diverse applications from DNA profiling to protein characterization, quality control and beyond.
