Gel electrophoresis

Pulsed-Field Gel Electrophoresis (PFGE)
An electrophoresis technique for separation of large DNA. Alternating electrical field is applied to run DNA through a low density agarose gel matrix.

Gel electrophoresis
The process of separating charged species by subjecting them to a voltage gradient. A gel (made of agarose or polyacrylamide) provides mechanical support and prevents mixing of the molecules being separated.

The DNA is digested using restriction enzymes and separated using gel electrophoresis as described above.
The fragments on the gelatin are transferred to a filter by blotting.

The gel can be made so that its pores are just the right dimensions for separating molecules within a specific range of sizes and shapes. Smaller fragments usually travel further than large ones. The process is sometimes called gel electrophoresis.
