os·mot·ic shock

a sudden change in the osmotic pressure to which a cell is subjected, usually to cause it to lyse.

osmotic shock

n.
The rupture of bacterial or other cells in a solution following a sudden increase in intracellular osmotic pressure. Osmotic shock is sometimes used to induce cell lysis for the purpose of releasing the contents of the cell.

The collection medium used with an impinging type sampler should prevent osmotic shock of vegetative organisms.
Immobilization also may decrease the rehydration rate and avoid the osmotic shock associated with instantaneous rehydration, which subsequently decreases the growth and acidification lag phase.
On July 14, PROFEPA finally issued its 500-plus-page report, which concluded that: "A spill causing an elevated concentration of saline and other minerals which provoked an osmotic shock or variation in the salinity of the sea water was the cause of death of 94 sea turtles."
This aggravated the post-cyclone mineral imbalances which, combined with osmotic shock, touched off the white spot outbreak.
Distilled water was used during the first seven days and, from the eighth day on, water with increasing EC values was used in order not to cause osmotic shock. Thus, all pots were equilibrated with the EC values corresponding to the treatments at 16 days after planting (DAP).

Periplasmic expression has several advantages over the cytosolic one as follows: i) it simplifies protein purification, ii) it maintains an oxidizing environment to promote proper protein folding, removal of signal peptide and elimination of polypeptides, iii) the outer membrane can be selectively degraded by simple osmotic shock, iv) the periplasm is accessible to molecules, e.g.
"By creating an osmotic shock around the site of the injection, we create an inflammatory response in the tendon, which may be absent in some patients.
