Custom Development Capabilities

Cell-based assays are valuable tools employed throughout the drug discovery and development phases and into commercial release and stability testing. Implementing cell-based assays for in-house custom assay development can be challenging, from establishing physiological relevancy to method qualification, validation, post-implementation, and support. Phase-appropriate assays, in particular, can be technically challenging, expensive, and resource-intensive, delaying moving programs forward to the clinic.

Eurofins DiscoverX® offers the industry’s most extensive off-the-shelf menu of cell-based assays that can be implemented for your programs. Several customized solutions can be delivered for program-specific needs by utilizing our deep expertise in cell line engineering, assay design, method qualification, and cell and protein production. Some solutions include engineering a cell line with a different cell background, target, or cell model; developing an assay with a unique mechanism of action (MOA); or creating a ready-to-use bioassay qualified with your clinical molecule.

Gain from our experience leveraged over 20 years of custom development expertise and a vast history of generating thousands of customized assays for drug discovery programs at multiple companies globally through screening, lead optimization, and bioanalytical assay development.
