Gel electrophoresis

Electrophoresis is a common molecular biology technique that is used to separate biological materials by virtue of their size and/or charge.

In a gel electrophoresis experiment:

• An electrical field prompts negatively charged material to migrate toward a positively charged cathode through a fibrous gel matrix.
• The speed at which nucleotide chains and proteins migrate through the surrounding gel matrix is dependent upon their molecular weight.
• Researchers can use this information identify specific components by virtue of their size.

Identification of specific nucleotide and protein components in electrophoresis is made possible through use of a carefully controlled set of molecular weight markers, colloquially known as a “ladder”.
