Whether you need to clone a gene, detect a specific nucleic acid sequence, or quantify DNA or RNA, you need a complete set of genomic analysis tools that work together. We offer an extensive collection of high-quality reagents and chemicals for DNA and RNA gel electrophoresis and blotting including DNA and RNA ladders, sample loading buffers, precast agarose gels, nucleic acid stains, nylon transfer membranes, hybridization solutions, and Northern and Southern blotting reagents and consumables. 

What is gel electrophoresis used for? Gel electrophoresis is often used for separating molecules, such as protein, DNA, and RNA, by their size. Enhance your nucleic acid gel electrophoresis workflow with our DirectLoad™ Mini and Midi Horizontal Electrophoresis Systems. Buffers, ladders, loading dyes, and stains complement a compellingly economical solution for agarose gel electrophoresis. Featuring unprecedented sample throughput and experimental versatility, explore the full list of offerings within the DirectLoad™ lineup of products and optimize your nucleic acid research.
