One all of the wells are loaded, an electrical current is run through the gel to move the molecules.
Voila! Results! Look closely and you can see that the black in the first well (on the bottom), has actually separated out into a purple and an orange. Blue is the largest molecule and therefore it moved the shortest distance. Gels were made with 2.5g agarose and 250mL 1x TAE buffer and run for ~ 20 minutes.

Hi Honors Biology @ Lawrenceville,
I am searching for a cheaper way to perform the food dye electrophoresis lab, but have been unsuccessful getting clear bands as pictured in your results. Did you make your own dye solutions, and if so, what does it contain? Thanks for any info!
