The two main types of Electrophoresis are gel electrophoresis and capillary electrophoresis. Gel electrophoresis involves running a sample through a gel matrix, usually made of agarose or polyacrylamide, which creates a size-based separation. Capillary electrophoresis, on the other hand, involves running a sample through a narrow tube, or capillary, which creates a separation based on charge and size.
In Gel Electrophoresis, the sample is loaded onto a gel matrix, usually made of agarose or polyacrylamide, which is then placed in a buffer solution and an electric field is applied. The gel matrix acts as a sieve, slowing down the migration of larger molecules, such as DNA fragments or proteins, and allowing them to be separated based on their size. The separated molecules can then be visualized using various staining techniques or transferred onto a membrane for further analysis.
In Capillary Electrophoresis, the sample is injected into a narrow tube, or capillary, filled with a buffer solution. An electric field is then applied, causing the molecules in the sample to migrate towards the oppositely charged electrode. As the molecules migrate through the capillary, they become separated based on their size and charge, with smaller molecules migrating faster than larger ones. The separated molecules are then detected as they pass a detector located at the end of the capillary.
