Who invented electrophoresis

Life Arne Tiselius grew up in Stockholm, Sweden. Work If an electrical charge is laid over a sheet of damp paper on which lie a few drops of a solution containing electrically charged molecules, then the molecules will begin to migrate along the electric field.

In fact, the separation technique was first developed for use by scientists way back in Since then, researchers, chemists, and technicians have utilized electrophoresis to separate different charged particles with the use of an electric field.

This can be used in the analysis of everything from DNA samples to pesticides and environmental pollutants. Over the last couple of centuries, the process has become more and more sophisticated and advancements are frequently being made.

Although electrophoresis was first discovered in the early 19th century, it was not commonly implemented in scientific applications until During electrophoresis, a sample is exposed to an electrical current. Positively charged ions move toward a negative electrode and negatively charged ions move toward a positively charged electrode. Since different ions migrate at different rates, they can be effectively separated through electrophoresis.

There are several different kinds of electrophoresis, but one of the most common for laboratory applications is nucleic acid gel electrophoresis. With gel electrophoresis, the biomolecules in nucleic acids and proteins are separated in a gel after being exposed to a field of electricity.

At the time that electrophoresis was first introduced for DNA and RNA applications, nucleic acids were primarily separated based on sedimentation velocities through centrifugation.
