Cell-based assays are a cornerstone of drug discovery. They play a vital role at every stage from early target validation and compound profiling to late-stage mechanism-of-action studies.

Developing robust and relevant in vitro and ex vivo cell assay solutions is essential for making informed decisions at the right time. At Sygnature Discovery, our team of expert cell biologists design tailored assays to fully characterize and validate your targets, helping you advance compounds from hit validation through candidate selection.

Our Approach to Cell-Based Assays

Choosing the right assay is critical to your program’s success. Early in discovery, recombinant overexpression cell assays are often ideal, they’re high-throughput, easy to interpret, and optimized for identifying compounds that interact with your target. These systems can include related family members for selectivity studies or species homologues for cross-reactivity assessments.

As programs progress, confirming target engagement in physiologically relevant cells become essential. That’s why we provide assays using human iPSC, primary cells and ex vivo tissues. Our scientists design complex phenotypic assays in 2D and 3D formats, characterizing signalling and expression patterns to predict functional outcomes. Medium- to high-throughput assays allow rapid profiling of novel compounds, gene expression analysis, and biomarker identification.


Choice of Cell System

Selecting the right cell system is the first step. We offer:

Recombinant Cell Systems:

Overexpressed targets for sensitive detection.

Disease-Relevant Models:

Cancer lines, human primary cells, iPSC-derived cells

Our team works with you to design assays that monitor ligand binding, intracellular signalling, and functional outcomes. Combining data from multiple assay types accelerates progression from hit-to-lead through preclinical proof-of-concept.
