In this series of blog posts, we challenge the traditional one-factor-at-a-time (OFAT) approach to doing science, which most of us were taught in school and continue to use until now. This approach studies the effect of a single component (factor) on a biological system, ignoring other potential components and any interactions between them. We argue this method is reductionist and often results in the loss of information and insights.
Design of Experiments (DoE) is a powerful alternative to OFAT as it studies the effects of a multitude of factors and their interactions simultaneously, allowing scientists to explore a wider assay design space and to optimize the conditions for the system under investigation more effectively.
However, sophisticated DoE assays cannot easily be executed manually and hence rely on lab automation, which comes with its own complexity and challenges. To overcome them, we have developed a flexible and user-friendly software platform that can seamlessly program a range of automation devices, such as liquid handling robots, to execute sophisticated experiments, without the need for any programming input from the user. This makes it an intuitive platform for biologists with no programming background.
We touched upon the Synthace platform's benefits in Part 1 and Part 2 of the series, but how exactly does it work? Here we explore its capabilities in more detail. For a full demonstration of it in action and to see how it enabled us to perform sophisticated 486-run DoE for buffer optimization, please watch our online demo here.
Codeless Interface for Simple Execution of Sophisticated DoE Assays
The Synthace platform interprets simple user- or third-party software-generated CSV files describing the DoE conditions (different factors, their levels, and combinations). It then propagates that information through a digital workflow encoding different experimental steps. Finally, it translates the workflow into a set of liquid handling instructions for a selected liquid handling robot, programming it to execute the experiment. Modifications can be easily brought to the design file and/or the workflow, and the Synthace platform updates the liquid handling instructions accordingly.
Even the hard-to-encode factors, such as incubation temperature, can simply be included in the input design file. Similarly, sophisticated DoE operations, such as staging and factor fixing, can also be easily inputted into the Synthace platform by the user. It then plans and calculates the most optimal way to set up DoE assays, including splitting the reactions into different plates when needed, and programs the liquid handler to execute the experiments without user programming inputs.
Ultimately, the Synthace platform allows for considerable time and resource savings by simulating the designed experimental workflow in silico before the physical execution in the lab. In this way, calculation errors, missing experimental parameters, or even physical liquid handler constraints are taken into account, preventing the errors in the physical execution that would fail the whole experiment. Users can therefore correct and optimize their workflow as required to ensure experimental success and avoid wasting time and resources on trial-and-error runs.
Moreover, each liquid handling step of the experiment can be previewed as a result of this simulation, providing complete traceability of each sample and its components. This means that the same workflow can be used by multiple scientists/labs and on multiple liquid handling robots while retaining its robustness and ensuring data reproducibility. If needed, the workflow can be easily modified for a different use case due to the built-in flexibility of the Synthace platform's interface.
How Can Synthace Help You Optimise Your Assays?
Overall, it leverages the strengths of lab automation to execute sophisticated experiments, such as DoE assays, rapidly and seamlessly, without requiring programming knowledge from the user. With the Synthace platform, DoE-driven optimizations are made simple, design modifications are easy to incorporate, and the resulting workflows are straightforward to share and reuse.
Ultimately, it empowers biologists to perform more sophisticated experiments, explore a greater design space, and gain insights that cannot be achieved otherwise, without compromising on time and resources. All this improves the quality of science: for instance, faster and more effective buffer optimization for construct assembly assays can dramatically increase their success rate, facilitating downstream bioprocessing.
