Webosmotic agents, pH buffers, and sometimes nutritive ingredients or apoptosis inhibitors. The ingredients are usual-ly present at near isotonic concentration (300 milliosmoles) so that cells neither shrink nor swell when held in carrier solution. Carrier solu-tion is sometimes called “base perfusate.” The carrier solution typically used with ... The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a semipermeable membrane. Only molecules or ions with certain properties will be able to diffuse across such a membrane. This is a very important mechanism in biology wher… gdot inroads design manual
