Electrophoresis gels are a foundational consumable for gel electrophoresis workflows used to analyze DNA samples, proteins, and other macromolecules. Used across PCR, biotechnology, and molecular biology applications, electrophoresis gels enable the separation of DNA fragments and proteins by size under an electric field, supporting accurate visualization, analysis, and downstream blotting techniques.
Types of Electrophoresis Gels
Pre-Cast Gels
Precast electrophoresis gels offer convenience, consistency, and reproducibility for routine and high-throughput workflows. These ready-to-use gels eliminate preparation time and variability while supporting reliable gel run performance. Precast formats are available for agarose and polyacrylamide gel electrophoresis, making them suitable for DNA, RNA, and protein analysis across a wide range of assays.
Features and Benefits of Electrophoresis Gels
Electrophoresis gels are designed to support reliable separation, clear results, and efficient laboratory workflows.
- Enable gel electrophoresis for the separation of DNA fragments and proteins
- Consistent pore size supports the resolution of different sizes and molecular weight ranges
- Compatible with PCR products, plasmid DNA, and genomic DNA samples
- Support the separation of DNA fragments measured in base pairs
- Suitable for agarose and PAGE (polyacrylamide gel electrophoresis) workflows
- Precast options reduce hands-on time and improve reproducibility
- Designed for a uniform electric field distribution between each electrode
- Compatible with common buffer solution systems and reagents
How Electrophoresis Gels Work
During a gel run, DNA molecules or proteins migrate through the gel matrix under an electric field. Smaller molecules move more quickly through the gel pore size, while larger macromolecules migrate more slowly, resulting in the separation of DNA fragments by size.
- DNA bands resolve based on molecular weight and fragment length
- Separation progresses toward the end of the gel near the positive electrode
- Buffer solution maintains conductivity and sample stability
- Denatured samples can be analyzed using SDS or PAGE formats
- Results are visualized using UV light and compatible stains
