A collection of organic cations has been used to probe the gross structural features of the ionic diffusion pathway in a K+-selective channel from sarcoplasmic reticulum (SR). Channels were incorporated into planar phospholipid bilayer membranes, and single-channel currents were measured

It is hypothesized that buffers capable of forming a Schiff base with the PLP of gamma-aminobutyric acid aminotransferase (GABA-AT) may lead to denaturation and inactivation of the enzyme. On the basis of this hypothesis three new methods for the selective

An EOF counter-balanced ITP boundary has been used to stack anions from high conductivity samples during continuous electrokinetic injection of the sample. In a polystyrenesulfonate/poly(diallyldimethylammonium chloride) polyelectrolyte coated capillary, the time at which the ITP boundary exited the capillary could
