Xenopus oocytes serve as a standard heterologous expression system for the study of cloned ion channels. The large size of these cells allows for relatively easy expression and recording of activity of exogenous ion channels (together with neurotransmitter receptors and/or various regulatory proteins) using the whole-cell two-electrode voltage clamp (TEVC) technique, as well as standard single-channel patch clamp recordings. Although usually advantageous, the cell size also dictates certain limits on the accuracy of recordings and requires specific modifications of recording methods. However, combining the advantages of the system with available recording methods enables the use of Xenopus oocytes for sophisticated multidisciplinary studies of ion channels.
