DNA Fragment Size Determination

The Multi-functional Horizontal Electrophoresis Tank (DL-SUB03) is a large-format, high-throughput horizontal gel box designed for DNA and RNA fragment separation, PCR product confirmation, restriction fragment analysis, and nucleic acid quality assessment in high-volume clinical diagnostic and research laboratories . Featuring five interchangeable gel trays (200 × 200 mm, 200 × 130 mm, 130 × 200 mm, 130 × 130 mm, 130 × 65 mm) and multiple comb configurations (0.75 mm, 1.0 mm, 1.5 mm thicknesses with 8-well, 11-well, and 2-well options), this system provides resolution of nucleic acid fragments from 5 to 2500 base pairs with 10 base pair resolution and a maximum sample load of up to 200 samples per run .

For the molecular biologist and clinical laboratory scientist, the DL-SUB03 supports high-volume PCR product confirmation for infectious disease testing (COVID-19, influenza, hepatitis, HIV, respiratory virus panels, gastrointestinal pathogen panels), DNA fragment analysis and size determination with 10 bp resolution, restriction fragment length polymorphism (RFLP) analysis for genetic screening (sickle cell disease, cystic fibrosis, BRCA mutations), multiplex pathogen detection, nucleic acid quality assessment for molecular diagnostics, gel extraction for downstream applications, and sequencing sample preparation .

Constructed from high-strength, high-transparency plastic with UV protection, the DL-SUB03 provides a clear view of the electrophoresis process while protecting operators during UV visualization. The interchangeable tray and comb system allows rapid adaptation to varying sample volumes and throughput demands, with gel inspection window for monitoring progress without opening the cover . A free gel tray is included with the system .

For the patient undergoing molecular diagnostic testing for infectious diseases, inherited genetic conditions, or oncology biomarkers, the DL-SUB03's high-volume capacity (up to 200 samples per run), high-resolution fragment separation (10 bp resolution), and reliable DNA fragment analysis ensure accurate PCR product confirmation, restriction fragment analysis, and nucleic acid quality assessment—supporting reliable diagnostic results that guide appropriate treatment decisions across molecular diagnostics, genetic screening, and clinical pathology applications.
