Voice-powered Method-dev for Protein Expression in Lab of the Future

When the human genome was sequenced in 2003, it became possible to identify the gene and protein changes that occur in various diseases, such as cancer. Ever since, the field of proteomics has been booming to respond to the ever-increasing prevalence of chronic diseases. Today, the global market for therapeutic proteins is valued around US$100 bil- lion.

One of the major problems faced by biopharmaceutical companies is clinical trial fail- ures—only 12% of drugs tested in clinical trials will get marketing approval. This means that, on average, companies must develop and test around eight compounds in order to get one approved. Companies are looking to improve these odds by employing new tech- nologies, such as artificial intelligence (AI), alongside traditional tools like mass-spec- trometry (MS) or high-performance liquid chromatography (HPLC).

Complex technologies can produce very large datasets and scientists now face the chal- lenge of managing huge amounts of data. Accurate documentation is key to getting the most value out of experimental data. For example, method-development entails constant adjustment of multiple parameters and therefore requires precise documentation of each step and decision.

Planning an experiment involves updating and printing several protocols and then carrying these protocols around the lab. Once at the bench, scientists often add notes to protocols during experiments. Paper loss between different workstations, damage from chemical spots, as well as difficulties reading protocols while performing experiments, are daily challenges faced by scientists.

The lab of the future - Preparing an Experiment

By loading or updating protocols in LabTwin, scientists can access their protocols, simply by using their voice, anywhere and at any time. Scientists can also create a label at the beginning of each workflow. LabTwin will then tag every note taken during this workflow. At the end of the experiment, the scientist can easily collect all notes and details by using this label.

Scientists report that LabTwin helps them prepare for experiments by simplifying the process of capturing ideas and adding any missing lab items or reagents to an order list.

the planning phase and gather them in one place.”

The first step in protein production is to express the protein in a cell line. Culture conditions need to be optimized to maximize cell survival (pH, temperature, cell density, etc). Most of the work is carried out under a sterile hood and scientists have to wear gloves to avoid contaminating their cultures. These conditions make it difficult for scientists to read protocols or write down observations without interrupting their workflow. Therefore, researchers often try to memorize a lot of information, for example the position of various samples within a 96-well plate, until they can access a computer.

LabTwin’s voice-activated digital lab assistant is hands-free and allows scientists to work seamlessly at the hood. The digital assistant reads out protocol steps and imme- diately captures observations, such as batch numbers or sample positions. Scientists save time and strongly reduce contamination risks by keeping their hands gloved and focused on their experiment.

“Before LabTwin, I was relying on my memory to report
which samples are in which positions.”

The Lab of the Future - Small Scale Culture of Transfected Cells


Once optimized, scientists then scale up a cell culture in order to produce a large amount of protein. Bioreactor tanks are the most common tool for large scale culture and provide multiple settings of various parameters, such as pH, temperature, osmolarity, oxygenation and stirring. These experimental condition data and metadata are very useful for troubleshooting. Moreover, cultures need to be monitored for several days, increasing the complexity of documentation.

With LabTwin, scientists can effortlessly record the multitude of details which need to be collected over days during a large-scale culture. In average, scientists record 34% more details with LabTwin than they were doing before. Moreover, LabTwin provides integrated reminders so scientists don’t forget to check their ongoing cultures.

After several days of culture, scientists then isolate proteins from component cell parts. Several methods of protein extraction exist, from sonification to cell lysis, and each method should be tested and optimized to maximize recovery of intact proteins. Scientists usually document each sonification parameter (number, duration, burst frequency) in order to be able to repeat successful experiments, troubleshoot unsuccessful experiments and create protocols.

the extra details are what help them to make the experiment a success.”

The extracted proteins are then sorted by High-Performance Liquid Chromatography (HPLC) to isolate the protein of interest.

Scientists report being able to record more details about each experiment using LabTwin, compared with previous documentation methods, which in turn makes it easier to troubleshoot or reproduce experiments. 84% of the scientists declare that LabTwin improves troubleshooting.

With LabTwin, researchers can list the different parameters used and describe their results, simply by talking. The voice-powered digital lab assistant then automatically transcribes all voice notes into written text.

The Lab of the Future - Protein Purification


Once a protein is isolated, several tests are conducted to assess protein purity and integ- rity. The classic electrophoresis gel can check purity, while mass spectrometry analyzes integrity. Chromatography systems or spectrophotometers can also be used to check and quantify proteins. Collecting information from all these different devices, often in differ- ent formats (manual notes, screenshots, print-out), can take more than a day.

With LabTwin, all notes and pictures are automatically gathered in one place, saving scientists a significant amount of time, reducing data loss and enabling real-time da- ta-driven decisions.

Moreover, scientists report particularly enjoying being able to set up multiple labelled timers within the LabTwin app. One scientist shared his satisfaction at not having to carry around and mix up five different kitchen timers to complete his experiments.

“I have to make decisions very quickly depending on a particular outcome. 
Real-time recording and accessing information is a great help.”

Each workflow ends up with scientists analyzing results and preparing reports. To do this, scientists often need to collect notes from different sources, transcribe them from manual to digital format and then upload them to either store or share with colleagues.

With LabTwin, scientists can take voice notes at the bench and have these automatically transcribed while they work. Then when researchers finish their experiments, they can quickly source all relevant notes in the LabTwin Web Platform using the label they chose for a particular experiment.

Scientists report that using LabTwin helps them save time and energy, and produce better quality reports.

The Lab of the Future - Analysis and Reporting


Documentation is very important for method development as each experiment is unique and will need to be reproduced if successful. LabTwin’s voice-powered digital lab assistant aids with method development by enabling scientists to record every parameter set as well as any deviation occurring throughout an experiment. This richer, real-time documentation facilitates troubleshooting and improves reproducibility. Ultimately, LabTwin saves scientists time by reducing the number of unsuccessful experiments.
