Determining lowest osmotic pressure
WebApr 12, 2024 · Osmolysis is a simple, low-cost method of cell lysis that relies on osmotic pressure to swell cells and burst membranes following the resuspension of cells in a hypotonic solution (Fig. 1A). Osmolysis as a cell lysis technique in downstream separations has traditionally been restricted to mammalian cell culture, where the weaker cell … WebThe net filtration pressure (NFP) represents the interaction of the hydrostatic and osmotic pressures, driving fluid out of the capillary. It is equal to the difference between the CHP and the BCOP. Since filtration …
