Ion channel electrophysiology in pharmaceutical research

23 May 2007 | By Daniel Konrad, Simon Hebeisen, and Urs Thomet, bSys GmbH

Ion channels are well recognised as targets for a vast range of disease states and conditions. The process of discovering drugs is influenced by the biological confidence in the rationale of the screening approach and the screenability. Various methods have been gathered around the gold standard of manual patch-clamping that…

High throughput electrophysiology platforms as enablers

25 January 2007 | By Peter Haddock, PhD., Pfizer Global Research and Development, CNS Pharmacology

Ion channels play key roles in regulating cardiac, neuronal and secretory tissue function. As such, the pharmacological modulation of ion channel activities may provide an effective means to positively impact upon an array of disease states. However, the reliance on low-capacity manually operated electrophysiology screening systems has dictated that ion…

Four years and counting for automation

20 July 2006 | By Claire Townsend, Ph.D., Investigator, GlaxoSmithKline

As a classically trained electrophysiologist, I shall always remember my first encounter with automated patch clamp at Essen Instruments in June 2002. Essen Instruments had just developed the IonWorks HT, an instrument that can record currents from 48 cells simultaneously and perform up to 384 recordings with a drug addition…
