Abstract: Methods, including high-throughput methods, for identifying modulators of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels.

Abstract: A system and method for high throughput patch clamp measurements to study the effect of various chemicals on ion transfer channels is provided. One or more patch clamp configurations is established, each comprising a cell sealed to a pipette. The pipettes are affixed to a pipette fixture. The pipette fixture and a plate comprising one or more wells are relatively moved so that each cell is inside a well. Electrical properties of the cells are measured.

Abstract: A system for carrying out fast perfusion for the patch clamp techniques useful in studying the effect of compounds on ion transfer channels in biological tissue is disclosed. The invention additionally includes microperfusion chamber assemblies capable of utilizing small amounts of material to be tested and small amounts of liquid carrier, thereby enabling multiple tests to be completed in a short period of time. The invention more broadly relates to an electrophysiology drug handling and application set up for screening chemicals such as drugs while providing high throughput and low volumes of solutions and samples.
