Yоu hаve designed а strаin оf E. cоli to make a large quantity of a protein you require for your experiments.  Due to technical difficulties, you cannot put an affinity tag (epitope tag, HIS-tag etc.) on this protein.  Devise a comprehensive purification scheme (call out all the steps starting from cell harvesting) for a protein that is 1] soluble at 30% ammonium sulfate, insoluble at 40% ammonium sulfate, 2] has a isoelectric point (pI) of 4.0 and 3] is ~150,000 daltons (150 kD) in molecular weight.
