Polyacrylamide gel electrophoresis provides very high resolution of DNA molecules 10–3,000 bp long. Under the appropriate conditions, DNA molecules differing in size by only a single base pair can be resolved (learn more: Nucleic acid electrophoresis education ).

In the nucleic acid electrophoresis workflow, several steps are performed sequentially, each of which could impact the outcome of nucleic acid separation. This article addresses five considerations associated with samples, reagents, and running parameters.

Gel electrophoresis is a common laboratory technique to isolate nucleic acids and proteins. Nucleic acid electrophoresis uses a gel matrix to separate DNA and RNA fragments based on size and molecular weight. Gel electrophoresis is vital in all molecular biology workflows.

DNA electrophoresis is a standard laboratory technique used to identify, quantify, and purify DNA fragments. DNA electrophoresis involves loading DNA samples into the wells of an agarose or acrylamide gel and subjecting it to an electric field.

Electrophoresis is a common lab technique used to identify, quantify, and purify nucleic acid fragments and assess quality. RNA molecules are negatively charged, and during gel electrophoresis they migrate toward the anode in the presence of an electric current.
