Many experiments in cell biology require researchers to break open cells and then retrieve their contents. For example, the production of recombinant proteins in biotechnology relies on cell and tissue cultures--and cell disruption is essential to retrieving sought-after cell products. The technology used must be powerful enough to disrupt cell membranes and, possibly, cell walls, yet gentle enough so that the organelles and macromolecules inside the cells are not smashed, shattered, or boiled away.
