Gel electrophoresis:

Vertical Gel Electrophoresis: The electrophoresis in this system performed in a discontinuous way with buffer in the upper and lower tank connected by the gel slab. It has multiple modification in the running condition to answer multiple analytical questions.

Horizontal Gel Electrophoresis: The electrophoresis in this susyem is performed in a continous way and the electrophoresis is performed in the horizontal direction.
