* Cells taken from the freezer were complete cells. After sonication, cells were burst open. The organelles, plasma membrane, and internal proteins were all exposed in solution. Centrifugation allowed the heavier organelles and plasma membranes to sink to the bottom of the tube, forming a pellet, and remaining proteins or other lighter biological molecules in supernatant. This is an effective and simple way to purify proteins from prokaryotic cells. | |||
