Candy Electrophoresis Lab

        We completed a gel electrophoresis lab using dyes in candy and dyes given to us by the teacher. We prepared the dyes then set them to move through a certain gel to see which ones move faster and which ones move slower. The faster ones were the ones with smaller molecules, and our fastest was yellow 5. The slower ones were the dyes with larger molecules, and our slowest was the candy dye from blue m&m's.
        I believe citrus red 2 would move like yellow 5 because they are both small and thin, betanin would move like yellow 6 because it is long and narrow, carminic acid would move like blue candy dye from m&m's because it is wide and large, and fast green would move like purple skittles dye because it is very wide.
        I believe there are artificial food colors in dog food too to make the food appear more edible and the color could attract the dog.
