Abstract

ABSTRACT: Introduction : Automated patch clamp (APC) devices have become commonplace in many industrial and academic labs. Their ease-of-use and flexibility have ensured that users can perform routine screening experiments and complex kinetic experiments on the same device without the need for months of training and experience. APC devices are being developed to increase throughput and flexibility. Areas covered : Experimental options such as temperature control, internal solution exchange and current clamp have been available on some APC devices for some time, and are being introduced on other devices. A comprehensive review of the literature pertaining to these features for the Patchliner, QPatch and Qube and data for these features for the SyncroPatch 384/768PE, is given. In addition, novel features such as dynamic clamp on the Patchliner and light stimulation of action potentials using channelrhodosin-2 is discussed. Expert opinion : APC devices will continue to play an important role in drug discovery. The instruments will be continually developed to meet the needs of HTS laboratories and for basic research. The use of stem cells and recordings in current clamp mode will increase, as will the development of complex add-ons such as dynamic clamp and optical stimulation on high throughput devices.
