Cell Microarray Technology
Physiological system for detecting ligand-receptor interactions
Retrogenix’s unique cell microarray technology provides a fast, accurate and effective solution for discovering the human cell surface and secreted protein targets of antibodies, proteins, viruses and small molecules. This allows our global pharmaceutical clients to:
- overcome the critical deconvolution step in phenotypic drug discovery
- uncover novel, high quality and exploitable drug targets
- explore safety liabilities of lead candidates using the most comprehensive human expressed off-target system
Retrogenix’s biologically-relevant system detects specific interactions with a high degree of sensitivity. This unique tool uses proprietary arrays of expression vectors – encoding over 5,500 full-length human plasma membrane and tethered secreted proteins – spotted onto slides. Human cells grown over the top become reverse-transfected resulting in cell surface expression of each respective protein at distinct slide locations. The test molecule is applied and specific binding analysed and confirmed using an appropriate detection system.
Technology Advantages
Retrogenix’s broad coverage extends across the full spectrum of known plasma membrane and secreted protein sub-classes including, amongst others: G protein coupled receptors (GPCRs), ion channels, drug transporters, Ig superfamily receptors, cytokines, hormones, immunomodulatory molecules, enzymes and growth factor receptors.

Case Studies
Retrogenix’s results are now supporting patent applications, appearing in peer-reviewed publications and being presented at international conferences. Our case studies highlight a selection of these projects providing further details on receptor identification, target deconvolution and specificity screening for biotherapeutics such as CAR T cells and antibodies.
