Electrophoresis equipment is essential in molecular biology laboratories for the separation, analysis, and quantification of DNA, RNA, and proteins based on molecular size and charge. This technique plays a foundational role in genomics, proteomics, forensics, diagnostics, and biotechnology, providing researchers with precise tools to resolve complex biological mixtures.
Electrophoresis systems are composed of several core components, including power supplies, gel electrophoresis units, buffer systems, and imaging equipment. These systems allow scientists to run agarose gels for nucleic acid analysis or SDS-PAGE gels for protein separation and size estimation.
Power supplies provide the necessary stable voltage and current to drive the migration of charged biomolecules through gel matrices. High-quality power supplies offer programmable settings for constant voltage, current, or power, making them ideal for gel electrophoresis, electroblotting, and isoelectric focusing. Some models include timers, safety alarms, and multi-output channels for parallel runs.
Gel electrophoresis units, including horizontal agarose gel systems and vertical PAGE systems, are used to resolve nucleic acids or proteins with high resolution. Agarose gel electrophoresis is commonly used for DNA and RNA fragment analysis, PCR product validation, restriction digest profiling, and plasmid screening. SDS-PAGE units are used to separate proteins by molecular weight for applications such as Western blotting, protein purity assessments, and molecular weight estimation.
These tools are critical in workflows such as gene cloning, DNA fingerprinting, mutation detection, and biomarker discovery. In educational settings, electrophoresis kits are widely used to teach molecular biology techniques.
