Today, more than 90% of all approved drugs are coming from research on small molecules, but large molecules research is rapidly rising in prominence. The importance of drug discovery already constitute the lion’s share of the top 10 selling drugs worldwide.

Large molecules have gained more attention due to their mode of action, often achieving greater target specificity and potency than small molecule drugs.

Global academic-industry collaboration developing anti-venom antibodies

The development of snakebite antivenoms has remained largely unchanged for over a century. The tried and tested technique involved inoculating horses with snake venoms: the horse immune response generates antibodies that can neutralize the snake venom. However, these equine derived anti-venoms are time-consuming to make, can have limited efficacy and can cause immune responses in human snakebite patients.

Snakebites cause the most injuries and fatalities in developing countries, affecting some of the poorest regions in the world. A lack of research and therapeutic development led the World Health Organization to designate snakebite as a Neglected Tropical Disease in 2017.

Using the latest antibody engineering techniques and technologies Andreas Laustsen’s Tropical Pharmacology Lab, DTU, Copenhagen has approached this problem with innovative science and solutions in this much needed, but neglected, area of medicine. In a global collaboration across academia and industry with Sophion Biosciences (Denmark), IONTAS (UK) and the Instituto Clodomiro Picado (Costa Rica), they have bio-engineered antibodies to neutralise snake venom toxins.

Line Ledsgaard, a PhD student in the Laustsen lab, DTU, gave a talk on this groundbreaking work.

New Whitepaper: Automated Patch Clamp in Cystic Fibrosis Drug Discovery

In October 2020, Enterprise Therapeutics’ TMEM16A programme was acquired by Roche/Genentech. This acquisition was the culmination of a research and discovery journey initiated in 2014, with the goal of providing a novel treatment paradigm suitable for patients with cystic fibrosis and other muco-obstructive diseases.

In this new whitepaper, we describe how APC was instrumental in the success of Enterprise Therapeutics’ TMEM16A programme or as Martin Gosling (CEO) describes it “Automated
electrophysiology has been KEY not only in finding the chemistry start points but in supporting the programme through its entire lead optimization”.

First ever QPatch ll installation in South Korea

Sophion and SureMedical have successfully installed the first QPatch ll at SK Biopharma in South Korea. SureMedical worked closely with the new user to find the right APC solution for their needs and we are happy to say they decided on a QPatch ll system with temperature control. This solution is a perfect fit for them regarding throughput, obtaining true Giga-ohm seals in physiological solutions and being able to control the temperature accurately at the measurement sites.

Despite these Covid-19 times, installation and training went according to plan and the new users are up and running. We are sure that SK Biopharma will put their new QPatch ll to good use and continue to break new ground in drug discovery.

QPlate, a unique design enabling high performance automated patch clamp

The unique design of our QPlates provides many advantages. Among others 100% liquid exchange, giga-seals in physiological solutions and no need for electrode maintenance.

In this application report, we tell about the design and advantages of using microflow-based consumables for Automated Patch Clamp.

Learn how the QPlate materials make it possible to create giga-ohm seals with physiological solutions. See data demonstrating that 100% solution exchange can be achieved with 20 µL of solution.

From teenager to early adulthood

From the servers and the drawers, we can still find documentation from the founding years. Here pictures from the founding reception and pictures and drawings of the barracks behind NeuroSearch A/S that was the Sophion ‘home’ for the first year… as well as, ideas, visit reports and visions from 2000 and 2001.

On 5th July 2000, Sophion Bioscience was founded as a spin-off from the Danish pharmaceutical company NeuroSearch. It is hard to believe that 20 years have passed.

From the annals on our servers and a carefully written diary by Sophion’s first CEO Torsten Freltoft, it is fascinating to follow the first years after the founding. As with all start-ups chasing capital was a part of everyday life to secure the development of what ended up being QPatch. Also, longer entries about Fussball-tournaments and fun nights out at conferences take up a lot of space and of course the inauguration of the new facilities that were opened in 2001.


From “QPatch Vision” in 2004: Already in 2004 Sophion focused on strong, professional customer support and saw the support as an integrated part of the product offering. Today, more than 15 years later, we continue to drive the business with this customer focus, maintaining a large organization of Application Scientists and Field Service Engineers to support our customers.

With the launch of the QPatch in 2005, Sophion started manufacturing, and focus changed from securing capital for development to securing global growth. Around that time someone wrote in one of those vision statements, that were very popular in the ’00s, that potential users of the APC systems not only needed the system and measurement plates but that strong support from application scientists and field service engineers was needed by users and lacking from other vendors. Today, 16 years later we operate from the same principles, ensuring that our users are always supported by a dedicated team of Application Scientists and Field Service Engineers.

In the years from 2005-2010 new installs were booming and Sophion was on the list of fastest-growing companies in Denmark for four consecutive years. While production was busy ensuring supply for new users, R&D continued new developments on the QPatch introducing, among others, the worlds-first automated Rs compensation, ligand applications, QPatch HT (48), multi-hole QPlates and current clamp. All features that are now standard on all Sophion products and most commercially available platforms.

In 2011 a major transformation occurred when Sophion was integrated with Biolin Scientific. Although ‘only’ 11 years old at that point it forced Sophion to grow-up quickly as a company and we still benefit today from the professionalism and structure that was introduced in the Biolin years. A more efficient supply chain and financial reporting system, as well as our ISO 9001 certification, are all processes that we enjoy today and that made us better equipped for the future.

When Qube 384 was introduced in 2014 it changed the way ion channel drug discovery could be done. With 384 individual channels, patch-clamp experiments running primary screening could suddenly be performed. With the introduction of the stacker solution in 2015, it became possible to perform overnight unattended screens of up to 15 QChips, something which is performed routinely by leading CROs and pharma companies on Qube 384 today.

However, the integration into a larger corporation was not a commercial success, and in 2017 a management buyout resulted in Sophion again being “masters in our own house”. After that, things have speeded up again, as many of our current and new partners have noticed. With the introduction of QPatch II 48, QPatch II 16, Qube Opto, online V½ estimation, and the new improved temperature controller, our APC systems are now easier than ever to use, with more advanced features. Double-digit growth, year on year, for the past 4 years has put us in an interesting new situation where we are running more EU projects, more industry partnerships, and more academic collaborations than ever.

In 2020 Sophion Bioscience is stronger than ever, and despite a challenging “Corona-quarter” in Q2-2020”, the future looks bright and promising. While parts of the world are still in lockdown, the crates shipped from Copenhagen in the past few weeks are a sure sign that other parts of the world are opening up again.

With Qube and QPatch installs in all major pharmaceutical companies we are proud to have left our mark on the ion channel field for the past 20 years and plan to continue doing just that for the next 20 years as well.

“Good habits formed at youth make all the difference”     


We do not know what the future holds. In the first twenty years, we have managed not only to bring the world’s best APC platforms to market, combining high performance and data quality with a design that makes them so easy to use that patch clamping is accessible to everybody. We promised back then to “take the voodoo out of patch clamping”, and we believe we have achieved just that.

What we can promise you for the future; We will continue to be inquisitive and innovative. We will continue to push the boundaries, enabling ion channel drug discovery and adjacent fields by combining ease-of-use with performance. We will do that while honouring the vision from 2004 because we ‘choose to focus on customer support’.

Sophion – Empowering innovation in drug discovery

An increasing number of patents using QPatch data are published worldwide. More than 350 patent families have been published with the support of QPatch high-quality electrophysiology data since 2005. Last year alone 60 patent families were published supported with QPatch data and the rate of patents filed per year is increasing.

The majority of the patents are filed in the US (46%), with Japan and the UK as follow-ups (11% each) and Switzerland in close pursuit (10%). The remaining 22% comes from a variety of countries with China as the prominent with 5% of the patent filings and then Germany, Italy, Denmark, Sweden etc.
Not surprisingly the majority of patent applications come from big pharma like Shionogi, Dainippon, Novartis, AstraZeneca, J&J and Gilead, but surprisingly, many smaller pharmaceutical companies use the QPatch data as a part of their patent filing.


We are of course happy that QPatch is used actively, not only for drug discovery, compound characterization and cardiac safety studies, but are also that QPatch data is used in the patent filings worldwide.

Title: IPSC-derived motor neurons on the automated patch clamp platforms Qube and QPatch

Poster presenter: Application scientist Kadla Rosholm

Location: Exhibit Hall A-E – Poster board No.: B332


Human induced pluripotent stem cells (hiPSCs) can be differentiated into multiple cell types, including neurons and cardiomyocytes. This gives rise to a novel way of establishing human disease models, which in turn can be used for drug development in vitro. Ion channels represent highly attractive therapeutic targets in the nervous and the cardiovascular system, rendering electrophysiological studies of hiPSCs important for their usage in drug discovery. However, such studies have traditionally been limited by the labor-intensive and low-throughput nature of patch-clamp electrophysiology. Here we use our automated patch clamp systems Qube 384 and QPatch 48 in order to increase throughput and reduce timelines.
Our observations include channel expression versus time in culture, the pharmacological dissection of endogenous ion channels (e.g. Nav and Kv), identification of ligand-gated receptors, and recordings of action potentials using the current clamp feature. Also, we show the electrophysiology of a spinal muscular atrophy (SMA) and an amyotrophic lateral sclerosis (ALS) model. The disease model for SMA was derived by mutations in the SMN1 gene and shows enhanced sodium channel activity but no shift in the normalized current-voltage relationship. ALS was here mimicked by a single point mutation in the superoxide dismutase 1 protein (SOD1), D90A, which had previously been identified in recessive, dominant and seemingly sporadic pedigrees. Cells carrying this point mutation displayed larger sodium currents, which eventually led to neurofilament aggregation, neurite degeneration and other phenotypes. We could confirm that the electrophysiological effect could be reversed by point mutation to D90D.

Our measurements validate the feasibility of measuring hiPSC ion channel currents using the APC platforms Qube and QPatch. Altogether, these results can facilitate evaluating the use of hiPSC for early drug development and in extension personal medicine.

Title: Biophysical and pharmacological profiling of multiple voltage-gated sodium channel subtypes on QPatch II

Poster presenter: Application scientist Daniel Sauter

Location: Exhibit Hall A-E – Poster board No.: B285


Voltage-gated sodium channels (VGSC) are responsible for the initiation and propagation of action potentials in excitable cells. VGSC have been identified as excellent drug targets for treatment of pain, epilepsy and to other neurological disorders. Early compounds, however, were developed using empirical approaches. The identification of the molecular identity of VGSC in combination with technological advances, such as the automated patch clamp technique, provide the basis for a rational design of subtype-selective compounds.

To date, 9 functional mammalian isoforms (NaV1.1–1.9) have been described in the literature. The various subtypes differ in their expression pattern and exhibit distinct biophysical and pharmacological profiles. All have in common that they produce a transient inward current in response to membrane depolarization. During this process, the VGSC transitions from a closed to an open into an inactivated state. Interestingly, inhibitor compounds often exhibit different pharmacological profiles dependent upon the ion channel conformational state.

In the present study, the second generation QPatch (QPatch II; Sophion Bioscience) was used in combination with adaptive voltage protocols to investigate state-dependent inhibition of tetrodotoxin (TTX) and tetracaine on 8 different VGSC subtypes (NaV1.1-8). A first step was to determine the half-inactivation potential V½(inactivation) for each individual cell. This value was then used during the next steps as preconditioning pulse. Such an adaptive protocol allowed to determine IC50 values for both the closed and the inactivated state and reduce heterogeneity of the cells. Both IC50 values and biophysical parameters of the different subtypes align well with literature values.


Make sure to come and see us at booth #1703 at SLAS2019 in Washington DC. The conference will take place at the Walter E. Washington Convention Center.

Tecan publishing article about QPatch

We are proud to share with you an article published in Tecans latest journal about Sophion and our work with the QPatch. You can read the article here.

QPatch automated patch clamp

New paper on KCa2.X (SK) on QPatch

Small conductance calcium-activated K+ channels (KCa2.X, SK channels) are promising new targets for the treatment of Atrial fibrillation (AF), the most common type of arrhythmia. In a collaboration with Acesion Pharma, Bo Bentzen and his group revealed an inhibitory effect of some established AF drugs on SK channels using Sophion`s QPatch.   The paper benefits from QPatch`s capability to gain gigaohm seal resistances without relying on the presence of seal enhancing fluoride in the internal solution.
