In recent years various ionic channels have been reconstituted in planar lipid bilayers by which rigorous analysis of the electrical behavior of single ionic channels can be made. I have reviewed, in the first half of this article, practical techniques for forming planar bilayers and for incorporating channels into them. The second half deals with a structural analysis of the ion conducting pathway of the reconstituted K+ channel from sarcoplasmic reticulum solely by measuring its electrical properties. The electrical analysis of channel structure should be a promissing approach to bridge the gap between the electrical property and the molecular structure of channel proteins in lipid bilayers.
