Question: Assume you are purifying a protein on a weak cation exchanger (pH 7.5) and it comes off at 300mM salt. predict what salt concentraiton (lower, same, higher) the protein would come off if you used a strong cation exchanger. Explain the logic behind your prediction in terms of the differences between a weak and strong exchanger.
