METHOD FOR MEASURING ION CHANNEL ACTIVITY

摘要

The present invention discloses a human embryo kidney cell or cell line transfected with a GABA-gated chloride channel derived from an insect of the order of Lepidoptera, Diptera, Coleoptera, Homoptera, Acarina, Thysanaptera, Heteroptera, Hymenoptera or Isoptera and its use in a one-pot, high-throughput method for the measurement of the change in membrane potential in a cell or cell line. The method is particularly effective in measuring changes in membrane potential resulting from a compound acting on a GABA-gated chloride channel derived from a tobacco budworm.
