DNA refills for our 6-station biotechnology kits help you save on costs by allowing you to reuse instructions and use your own electrophoresis supplies. The Electrophoresis Reagent Refill complements these DNA refills by supplying materials needed to conduct electrophoresis of DNA for any of our 6-Station Refill Kits. The Electrophoresis Reagent Refill contains 4 g of agarose, 150 mL of 20× TBE buffer concentrate, CarolinaBLU™ concentrate, and 6 staining trays. All you need to provide is the electrophoresis equipment, instructions, and DNA samples from your favorite kit.
