Drug candidate screening methods are applied to discover compounds with activity against ion channel targets. The method may include modulating the transmembrane potential of host cells in a plurality of sample wells with a repetitive application of electric fields so as to set the transmembrane potential...http://www.google.ca/patents/US20040191757?utm_source=gb-gplus-sharePatent US20040191757 - High throughput method and system for screening candidate compounds for activity against target ion channels
