| The charge selective permeability facilitates the studies of the membrane transport mechanism by means of permeable ion probes. |
|
| The ion selective permeability of the rust composition component showed the anion permeability of the rust film. |
|
| The polymer of the invention comprise the repeating unit described above, thereby having high oxygen permeability and high oxygen or nitrogen selective permeability. |
|
| The leak elements, channels, and so-called facilitated transporters confer upon the cell membrane selective leakiness or, more properly, selective permeability. |
|
| The resting potential is dependent upon ionic equilibria and the selective permeability of the plasma membrane. |
|
| The selective permeability of the plasma membrane prohibits most exogenous agents from gaining cellular access. |
|
| It is therefore of interest to understand the molecular mechanisms for this selective permeability. |
|
| The bacterial membrane is crucial, irrespective of the metabolic status of the cell, as it provides selective permeability for cellular homeostasis and metabolic energy transduction. |
