Why is Rf value different?
Once you have done chromotography and split up all of the amino acids in the protein you will need to measure from the spot where the sample was first placed to the top of the chromatography paper where the solvent stopped being drawn up through it. Next measure from the sample spot to the centre of each of the amino acid spots. Then, to calculate the Rf value divide the amino acid spot distance by the distance the solvent travelled. If you get an answer greater than one then you are dividing the numbers the wrong way round.
