  Which of the following procedures might help you to obtain soluble, enzymatically active protein? Select all options that may be useful. Explain your reasoning.
  A. Make the bacteria synthesize protein A in smaller amounts.
  B. Dissolve the protein aggregate in urea, then dilute the solution and gradually remove the urea.
  C. Treat the insoluble aggregate with a protease.
  D. Make the bacteria overproduce chaperone proteins in addition to protein A.
  E. Heat the protein aggregate to denature all proteins, then cool the mixture.
