Cells were kindly provided by Charles River.

The effect of four compounds on hERG currents were investigated, using the CiPA voltage step protocol. Measured on the Patchliner the perforated patch methodology (Escin) and multi-hole chips (4 holes per well) were used. The IC₅₀ value of Cisapride was determined as 112 nM, Bepridil as 178 nM, Dofetilide as 33.9 nM and Diltiazem as 14.5 µM.

Dr. Carol Milligan - Statement about the Patchliner

   "In 2006 we purchased two of Nanion's very first Patchliner systems for our laboratories at the University of Leeds. We have been working with both systems very successfully for nearly four years now which is reflected in our recent high quality publications.
We operate both Patchliner systems on a daily basis, serving five different laboratories within the Faculty of Biological Sciences. Due to the diversity between the five groups, our Patchliners have been thoroughly put through their paces. This means that we have tested a large variety of different cells and a vast array of channel types, both endogenously and exogenously expressed. For example, we have investigated endogenous transient receptor potential (TRP) channels in human vascular smooth muscle cells and human synoviocytes. In addition, we have studied endogenous ion channels in primary astrocytes, human lymphoblasts and neutrophils, to mention a few.

The high data output has resulted in the production of an enormous amount of extremely good quality data using both native and primary mammalian cells. Our ability to make successful recordings from primary cells using the Patchliner is an extraordinary accomplishment, especially because the primary cell types that we work with are generally very difficult to record from using conventional patch clamp. Another impressive feature of this platform is its ability to perform routine intracellular perfusion which has enabled studies which might not have previously been attempted. We have also included our new technology as part of our annual 'Leeds Ion Channel Workshop' where it is well received. The Patchliner has turned out to be a show case project for us and has opened up new opportunities which I believe will play important roles in the future successes of research projects here in Leeds."

Dr. Chris Fanger - Statement about the Patchliner

   "We acquired the Patchliner because of its high data quality output combined with versatile and unique experimental features such as temperature control and internal solution exchange. In our TRP-channel initiative, we record from diverse ion channels and cells, and Patchliner quickly delivered accurate data with minimal assay development required. The data throughput is substantially increased by Patchliner’s innovative hardware and software, supporting short cycle times between experiments, minimal redundancy in compound screening and unlimited user control of the experiments. We are convinced that the Patchliner allows us to progress faster towards new discoveries, and at the same time it gives us a competitive edge because of its vast experimental flexibility".

Dr. Thomas Seeger - Statement about the Patchliner

   “The Patchliner is a very good choice for the Bundeswehr research center. This instrument possesses features and offers great versatility that allow a broad  range of experimental protocols on diverse cell lines and ion channel targets. The Patchliner cooling plate allows not only cooling of cells to ensure high quality recordings over a couple of hours with the same cell batch, but it also allows to accurately store temperature sensitive supplements or test compounds over the complete experimental time during the day. The Patchliner is a great system for our many electrophysiology projects which are used to find new therapeutical options.”

Marc Rogers - Statement about the Patchliner and CardioExcyte 96

   "It has been an absolute pleasure and privilege to work with Niels and the Nanion team over the past decade. I firmly believe that our two small, but independently minded ion channel focused companies, share a similar business ethos and a clear focus on delivering cost-effective solutions to our customers. In our extensive use of the Patchliner platform since 2007, my teams have benefited from the dedication of Nanion’s service engineers, application scientists, and bespoke data acquisition routines, whilst Nanion have benefited from seeing their products applied and adapted to real-world drug discovery projects and assays."

   "This fruitful working relationship has now been extended to our use of the CardioExcyte96 phenotypic assay platform, which we utilise to develop and validate human iPSC cardiomyocyte cell lines and assays to meet the post-hERG, predictive cardiac safety testing needs of the drug discovery industry”."

Prof. Dr. David Weaver - Statement about the Patchliner

   “To invest in the Patchliner was a straightforward choice for the Vanderbilt Screening Center. This instrument combines a set of features that was particularly important to us. (...) Unlike other planar patch clamp devices we considered, the Patchliner gave us full access to the  electrophysiology modes we require for a broad range of experimental protocols including voltage clamp, current clamp, standard whole cell, cell attached, and perforated patch configurations combined with a facile ability to exchange the internal solution. (...) In a short time the Patchliner has already begun to expand Vanderbilt investigators’ horizons regarding what they can accomplish with electrophysiology.”

Prof. Dr. Jerod Denton - Statement about the Patchliner

   "One of the biggest advantages of the Patchliner for our lab is that it enables students and fellows without formal training in patch clamp electrophysiology to begin generating meaningful data almost immediately. Instead of spending a couple of frustrating months learning the motor skills and hand-eye coordination necessary for conventional patch clamping with a microscope and micromanipulator, they spend that time designing and executing experiments, generating, evaluating and interpreting data and moving the project forward. The Patchliner also enables experimental flexibility that would be very difficult or impossible with conventional patch clamp rigs. For example, a talented undergraduate in the lab just finished up a series of intracellular drug application experiments. These studies would be difficult for the seasoned electrophysiologist and nearly impossible for an undergraduate student. However, the Patchliner allowed them to be completed in a very short period of time.

Another major advantage is that the Patchliner enables us to rapidly confirm or exclude hits from our primary fluorescence-based high-throughput screen using ­gold-standard electrophysiological methods. And the quality of the recordings rivals that of a conventional patch clamp rig. In fact, our first observations of pore "knock-off" of a new ROMK inhibitory small-molecule came from the Patchliner. These early observations from high-quality Patchliner recordings provided a clear ­direc­tion for subsequent mutagenesis work aimed at defining the binding site of this molecule within the cytoplasmic channel pore."
