Overview

Cell-based assays are essential in helping
us understand how healthy and diseased cells
react to pharmaceutical reagents, enabling the development of new drugs and therapies. 

These assays serve as the basis point for new platforms designed to replicate human cell physiology as accurately as possible to meet the demand for better and more accessible treatments. However, many systems in place are time consuming, resource intensive and still do not meet evolving consumer standards around environmentally friendly production and reduced animal testing.

What are cell-based assays?

Cell-based assays are experimental methods that use living cells to measure biological responses to compounds, genetic changes, or environmental conditions. By analyzing whole-cell behavior, such as cell viability, proliferation, or signaling activity, they provide a more predictive and physiologically relevant view of cellular function.

To generate reliable and reproducible results, these assays depend on precise cell seeding, gentle handling, and accurate liquid dispensing across multi-step workflows, making automation and standardization essential for success.

Precise and Gentle Cell Dispensing

Successful automation of cell-based assays requires an equal distribution of cells into hundreds or thousands of microwells. 

The UP.SIGHT is an automated single-cell dispenser with colony tracking imaging that quickly and gently dispenses cells into well plates without impacting viability. By reducing the hands-on time required to run cell-based assays, researchers can also reduce overall timelines and resources needed to complete these processes.

Multiplexed Low-Volume Dispensing for High-throughput Screening

High-throughput screening (HTS) of compound libraries, reagent compositions or drug concentrations requires fast and accurate liquid handling technology. This is critical for cell-based assays used in drug discovery workflows.

The I.DOT HT is a noncontact low-volume liquid handler designed to simplify and accelerate complex liquid handling steps. The system can readily dispense cells into standard microwell plates, including 1536 and higher density formats, while decreasing overall operation costs and reagent use.

Noncontact High-throughput Well Plate Washing

Constant media exchange is necessary to nurture cell-based assays, otherwise cell health and overall experiment quality decrease significantly. This process is not only time consuming but also sensitive, as incorrect plate handling can lead to contamination and other issues.

To minimize errors and speed up media exchange, the C.WASH PLUS reduces the number of wash cycles required, and the use of plastic, increasing turnover of assays all while minimizing the risk of cross contamination. It can also be easily integrated to many existing workflows.

Why Cell-Based Assays?

Increase overall
throughput and automate many steps

A workflow that contains just one of our platforms will see faster turnaround, whether it’s single-cell dispensing, live-cell monitoring or media exchange/cell washing. An entire workflow using our technologies will see a dramatic reduction in plastic use and hands-on time and, thanks to automation, a lower error rate, thus increasing assay quality and results overall.

Faster data turnaround

As a standalone device, the Cellcyte monitors cell growth in real time, providing a comprehensive analysis of ongoing experiments thanks to its powerful and flexible software. Combined with our liquid handling and single-cell isolation platforms, experiments can be set up, conducted and analyzed in a matter of days.

End-to-end
ready solutions

Futureproof your workflows with automation-ready devices that work great in combination but can also very well work as standalone devices.

Research Workflows

Our user-friendly devices can reduce hands-on time in even the most complex cell-based assays. For the initial experimental setup, the UP.SIGHT platform opens the door to clonal cell culture lines, which can be initially monitored in the platform for confluency checks. The next step of the experimental design is to create different growing conditions by supplementing the culture medium with specific substances/nutrients in different concentrations.

The I.DOT can significantly reduce the time spent in this step thanks to its 8-channel dispense head, which prepares the appropriate liquid conditions. Then, the CELLCYTE X provides real-time analysis of cell growth rates in different conditions, ensuring proper cell health and maintenance through the process.

The upkeep and media exchange can be done with the C.WASH platform for an efficient, fast and pipette-free workflow, minimizing the stress generated by excessive handling.
