High throughput screening (HTS) is used in the pharmaceutical industry to aid drug discovery. Large numbers of chemical compounds can be tested for biological activity using a range of techniques. The patch clamp technique remains the gold standard to test activity of compounds on ion channels and automated patch clamp (APC) is increasingly adopted in HTS labs as an alternative to conventional patch clamp given its increased ease-of-use and higher throughput. APC is employed in all aspects of drug discovery from hit finding and lead optimization through to target validation and safety testing. This is only possible due to the increase in throughput toward HTS capabilities, the compatibility with HTS workflows, and a lower cost per data point which can compete with other techniques such as fluorescence imaging (using, for example, the FLIPR™ instrument) and calcium imaging with the added benefit of real-time kinetics of drug effects. Indeed, all the major contract research organizations worldwide use APC for ion channel screening and cardiac safety testing. Increased automation, including unattended operation, is also an important factor for increasing throughput, and instruments can reliably work beyond an 8-h day provided they are serviced with enough cells, solutions, and compounds. For this to work effectively, data must be reliable with high success rates, low false positive and negative rates along with reproducible IC50 values.
