3B Scientific electrophoresis agarose gel separation of dyes kit. Introduce students to this valuable separation science in a safe and colorful manner. Unlike DNA and other molecules which cannot be seen during electrophoresis, this activity uses dyes that can be observed during the actual procedure, providing visual reinforcement of the forces driving molecular movement and separation in the electrophoresis process. Kit contains enough materials to run ten 20-milliliter agarose gels (actual number of runs may vary based on equipment.) Kit includes: 200-milliliters of 2 percent melt and pour agarose, 500-milliliters of percent X TBE buffer, 1 set of electrophoresis dye sample set.
