Electrophoresis in the industrial context refers to a laboratory technique used for the separation of charged molecules, such as DNA, RNA, proteins, or peptides, based on their size and electrical charge. This method is extensively used in biochemistry, molecular biology, chemistry, and clinical laboratories to analyze molecular components.


Electrophoresis operates on the principle that charged molecules will migrate in an electric field towards electrodes with opposite charges. The rate of migration depends on the strength of the field, the net charge, size, and shape of the molecules. In industry, this process is crucial for the quality control of biological products, forensic analysis, and the development of pharmaceuticals.

Application Areas

Electrophoresis is utilized across various fields within the industrial sector:

  • Biotechnology and Pharmaceutical Industries: For the analysis and quality control of products such as vaccines, enzymes, and proteins.
  • Medical Diagnostics: Used in the separation and identification of proteins and nucleic acids for disease diagnosis.
  • Research and Development: Helps in the identification, sequencing, and analysis of genes and proteins.
  • Forensic Science: For DNA fingerprinting and other forms of genetic analysis to identify individuals in criminal investigations.

Well-Known Examples

Examples of electrophoresis usage include:

  • DNA Fingerprinting: A common application in forensic science to match suspects to samples collected at crime scenes.
  • Protein Purity Testing: In the pharmaceutical industry, electrophoresis is used to ensure the purity and consistency of protein-based drugs.

Treatment and Risks

Operating electrophoresis involves several technical considerations and potential risks:

  • Equipment Sensitivity: Electrophoresis apparatus must be carefully calibrated and maintained to ensure accuracy and reproducibility.
  • Sample Preparation: Samples must be prepared under strict conditions to prevent contamination and degradation.
  • Safety: Handling and disposal of chemicals and biological materials used in electrophoresis require adherence to safety protocols to avoid exposure to harmful substances.

Similar Terms

  • Gel Electrophoresis: A specific type of electrophoresis where molecules are separated in a gel matrix.
  • Capillary Electrophoresis: Another variation that uses capillary tubes to separate molecules and is known for its speed and efficiency.


In the industrial or industry context, electrophoresis is a fundamental technique used for the separation and analysis of molecules based on their size and charge. Its applications are critical in fields ranging from pharmaceutical manufacturing to forensic science, playing a vital role in research, diagnostics, and quality control.
