Automated Patch-clamp: QPatch HTX and QPatch 16


The QPatch HTX and QPatch 16 are fully automated patch-clamp platforms that allow for the testing of up to 48 and 16 cells in parallel respectively. These are medium throughput machines great for confirming hits from larger screens and also for lead optimization. The QPatch machines offer high quality measurements with the formation of gigaohm seals. The platform can be used to assay both voltage-gated and ligand-gated channels and utilizes stable cell lines.
