DRUG-SEQ ALTERNATIVE High throughput RNA sequencing
Discovery-seq is a tailored method to facilitate transcriptomic phenotyping of thousands of samples. Used for compound screens, drug mode of action studies, and in general for projects that require high-throughput RNA sequencing.
Discovery-seq
Transcriptomics for thousands of samples
Discovery-seq is an in-house developed method to perform 3' bulk RNA sequencing on thousands of samples within one experiment. It is the method of choice to gather large-scale transcriptomics data for drug screens and other applications that require large bulk RNA sequencing datasets. It is compatible with most animal species' cell lines and organoid models. Projects with a low amount of samples are more suitable for our bulk RNA sequencing service.
The method exploits the same molecular biology as our current single-cell and bulk RNA sequencing methods. Hence, Discovery-seq is different from the more known DRUG-seq. In the Discovery-seq protocol, we have improved sensitivity and eliminated the PCR bias that can occur in DRUG-seq. Our aim was to develop a method with higher accuracy and lower cost.
Clients utilizing our Discovery-seq services send us washed and frozen cells/organoids in plates. Our protocol relies on a standardized workflow using multiple robots and automatized steps that ensure high-throughput and high-quality results. Our standard pipeline provides an exploratory report to assess the performance of the experiment and initial interpretation of the results, but we can also provide an end-to-end service, including custom data analysis by our bioinformaticians.
Discovery-seq is ideally suited to be integrated into existing screening workflows. Screening plates can be evaluated on viability assays, cell painting or high-content screening. Once the data has been acquired, it is as easy as washing the cells pellets/organoids, followed by snap freezing and submitting them to us to perform Discovery-seq. Multimodal data can then be integrated to have a better understanding of the impact of your experimental conditions.

Applications of Discovery-seq
Drug mode of action
Performing RNA sequencing on thousands of samples allows for a comprehensive understanding of the drug's mode of action across different cell types, conditions, or individuals. This analysis can identify common and unique gene expression patterns, enhancing the precision and reliability of the drug.
High-throughput compound screens
High-throughput RNA sequencing in drug compound screens allows for the simultaneous analysis of the effects of numerous compounds on gene expression. This can speed up the process of drug discovery by identifying promising compounds more quickly and efficiently, and can also provide insights into the potential side effects and therapeutic targets of these compounds.
Large-scale bulk RNA sequencing
Large scale studies analyzing on the effects of various conditions or treatments will benefit from Discovery-seq. For example, scientists can use it to understand how gene expression changes when the cells/organoids are exposed to different environmental conditions, or genetic modifications. Or, analyse exposure to a variety of perturbations, such as high-throughput CRISPR or siRNA screens.

FAQ
We currently support cell lines from any animal species, as well as, organoids.
The ideal seeding density is between 5,000 and 10,000 cells (or the equivalent for organoids), but we can work with as few as 2,500 cells.
We require the cells/organoids to be washed in PBS (maximum volume left behind: 10 µL) to avoid interference with our lysis and reverse transcription.
Our standard service includes the mapping of the sequencing reads, together with its quality metrics. We also provide an overview of the performance of each well in a plate, based on unique genes and UMI recovered.
