Facts (generated by robot; please edit if you find it inaccurate)
- The aerolysin membrane channel is formed by heptamerization of the monomer.
- The movement of ions in the aqueous medium as they approach the mouth (radius a) of a conducting membrane channel is analyzed.
- Sensing with membrane channel is a new way in screening for solute molecules and several promising examples are already shown [2,3,16,19,20].
- Sensing with membrane channel is a new way in screening for solute molecules and several promising examples are already shown [2,3,16,19,20].
- The predominant plasma-membrane channel is a strongly outward rectifying K+ channel (passing K+ easily out of the cytoplasm to the extracellular medium), which is activated by positive-going membrane voltages as well as by elevated cytoplasmic Ca2+ concentration and alkaline pH.
