Electrophoresis

Understanding Electrophoresis Equipment

Electrophoresis devices enable the separation of DNA, RNA, or proteins by applying an electric field to a gel matrix. Common types include agarose gel electrophoresis for nucleic acids and polyacrylamide gel electrophoresis (PAGE) for proteins or smaller DNA fragments.

Key components of electrophoresis setups are:

• Gel tanks and trays: Hold the gel medium where the sample migration occurs.
• Power supplies: Provide stable voltage or current to drive molecular movement.
• Gel casting stands: Allow preparation of custom gels for specific experiments.
• Imaging systems (optional): Detect and visualise separated molecules stained with dyes or fluorescent markers.

Buyers often consider voltage range, uniformity of field, gel size compatibility, and system modularity when selecting equipment. Electrophoresis is widely used in DNA fingerprinting, gene cloning, protein analysis, and biochemical assays.
