Abstract
Injection into Xenopus oocytes of RNA synthesized in vitro using the rat brain cDNA RCK1 as a template or nuclear injection of the cDNA results in the expression of functional potassium channels. These channels exhibit properties similar to those of the non‐inactivating delayed rectifier channel found in mammalian neurons and other excitable cells.
