When we analyzed our results, some of our experimental samples contained dyes that did not match the four reference dyes. For example, some of the dye bands, almost all of them, were a different size than any other of the reference bands. Additionally, the green color band was a different color than any of the reference bands. Our green color band also split into two, a blue and a yellow. However, all the dyes moved in the right direction. The green dye was the only one that had these abnormalities.
Betanin and Fast Green, would be the ones that would migrate similarly to the dyes that we examined in this lab, because they have overall negative charges unlike the carminic acid and citrus red 2.
Dog food manufacturers would be likely to put artificial food colors in dog food, because the artificially colored dog food would be more likely to sell to consumers, and because the color might affect the way dogs think about the food, the way it affects humans.
Artificial colors are usually preferable to natural food colors, because they make food look more appealing to consumers.
Two of the factors that contributed to the distance the colored dye solutions migrated, were size, and the voltage of the gel system.
The electrical current moved the dyes through the gel.
One side of the gel was positively charged and one side was negatively, which caused the molecules to separate according to their size. The dyes were negative, so they moved to the positive side. The speed was directly affected by their size.
If I used gel electrophoresis on molecules with 600, 1000, 2000, and 5000 daltons, I would expect the molecules which weighed more, would not move as far as those that were lighter. This would happen because the heavier molecules would be larger, and move slower through the gel electrophoresis process.
