Electrophoresis

The Objective : The objective is to determine what the relationship is between molecule size and pigment of food coloring dyes.

Methods/Materials

An electrophoresis chamber was constructed, and an agarose-based gel was used in the electrophoresis process.

Five dye samples were placed in the chamber and separated through electrophoresis in order to determine the relationship between molecule size and pigment color.

Results

The orange dye was found to have the smallest molecules, followed by purple, red, and then blue.

This dye order held true throughout the two hour electrophoresis process.

Conclusions/Discussion

The results of my experiment indicate that under certain conditions the dye pigment of lightest color has the smallest molecules. Further testing is needed to determine if this theory holds true under other circumstances.

This project is to use electrophoresis, that dye samples of lighter color have smaller molecules than dye samples of darker color under certain conditions.
