Patch-Clamp and Perfusion Techniques to Study Ion Channels Expressed in Xenopus Oocytes.
The Xenopus oocyte expression system is ideal for electrophysiological characterization of voltage-dependent and ligand-dependent ion channels because of its relatively low background of endogenous channels and the large size of the cell. Here, we present a protocol to study voltage- and ligand-dependent activation of ion channels expressed in Xenopus oocytes using patch-clamp techniques design...
متن کاملPatch clamp recording of ion channels expressed in Xenopus oocytes.
Since its development by Sakmann and Neher (1, 2), the patch clamp has become established as an extremely useful technique for electrophysiological measurement of single or multiple ion channels in cells. This technique can be applied to ion channels in both their native environment and expressed in heterologous cells, such as oocytes harvested from the African clawed frog, Xenopus laevis. Here...
متن کاملExpression of Ion Channels in Xenopus Oocytes
Xenopus oocytes have been widely used for studying ion channels in a controlled in vivo environment since the system was initially developed for this purpose by Miledi and coworkers [1, 2]. There have been at least five major types of studies using oocytes to examine ion channel expression. The earliest use was to examine the properties of specific ion channels in a living cell free from other ...
متن کاملInactivation of cloned Na channels expressed in Xenopus oocytes
This study investigates the inactivation properties of Na channels expressed in Xenopus oocytes from two rat IIA Na channel cDNA clones differing by a single amino acid residue. Although the two cDNAs encode Na channels with substantially different activation properties (Auld, V. J., A. L. Goldin, D. S. Krafte, J. Marshall, J. M. Dunn, W. A. Catterall, H. A. Lester, N. Davidson, and R. J. Dunn....
متن کاملSelective actions of a detergent on ligand-gated ion channels expressed in Xenopus oocytes.
Cytoclean a commercially available detergent, has selective actions on ligand-gated ion channels. Cytoclean (0.0005-0.01% v/v) potentiated 50 microM glycine responses in oocytes expressing alpha-2 glycine receptors by 23 +/- 7% to 342 +/- 43%. Cytoclean is composed of five components dissolved in water, but only one reagent, Bio-Soft D-62, modulated responses of oocytes expressing alpha-2 glyci...
