Method Researchers calculated the volume in these different cellular compartments by imaging a cytoplasmicly expressed fluorescent protein and a fluorescent outer-membrane dye either simultaneously or individually.
Comments Researchers observe two phases to the reduction in volume: an initial fast decrease and a later slower stage. The rate of volume reduction in the faster phase, dVn/dt, can be as high as 8% per second and depends on the magnitude of the osmotic shock.
