Cell Based Assay Development Service

Save Valuable Time For Your Research Project

Current drug development and toxicological testing strategies can be costly and often have high failure rates in later stages of development. Accordingly, cell-based assays are important tools for screening new drug candidates before moving on to expensive animal model testing. Our experienced assay experts are dedicated to accelerating your screening capabilities. With our many years of experience in cell-based assay development, you can save valuable time for your research project by outsourcing time-consuming workflows to us.

Pharmaceutical companies use a variety of approaches to drug discovery. Historically, large numbers of compounds have been tested in high-throughput biochemical assays. However, the complexity of disease backgrounds has increased the need for more physiological systems and the use of cell-based assays to predict the response of the organism. trenzyme specialises in cell-based assays using various cell lines and state-of-the-art technologies. Our highly skilled experts are able to develop customized cell-based assays and provide reliable results to help you accelerate your screening capabilities. In addition, together with our stem cell experts, complex predictive and translational in vitro assays can be combined with highly physiological human stem cell-derived cell types to provide advanced compound testing solutions.

What Our Clients Say About Us

We have expanded and tested the clonal cell lines and we are extremely happy with their performance. Needless to mention, that it was possible because the process of generation of cell lines at trenzyme was very efficient and robust. I would definitely be interested in getting the engineered cell lines from trenzyme in the future, if the need arises.

Cell Based Assay Development Service FAQs

What techniques do you use to measure endpoints?

We use a wide range of techniques to measure endpoints, e.g. FACS, Immunostaining, ELISA, Western blot and qPCR.

Based on which cell line types can you develop assays?

Our scientific experts can develop assays based on basic cell lines, customized cell lines or iPSC-derived cell types. For this, we use our in-house differentiation protocols with cardiomyocytes, hepatocyte-like cells or neurons for your analysis. Alternatively, you can provide us with your protocol so that after the technology transfer, our experts perform the work using this protocol internally at trenzyme.

Is it possible to order both, assay development and subsequent analysis of compounds?

Yes, our assay experts are delighted to develop an assay according to your needs prior to compound analysis.
