help with controls

Please help us. Our experiment involved the formol titration of hydrolyzed and unhydrolyzed peptides, to determine the amino acid sequence of a polypeptide chain. We also did work with silica strips to determine the Rf values of amino acids. What are the controls for our experiment? WE NEED HELP ASAP! Thanks!

We found our own answer, we think that the controls are the type of silica strips, size of the spots, and the point from which we measured. But, please let us know if this is right. Thanks!

I agree.
