Flexible Assay Technology for Studying Diverse Applications
Most Eurofins DiscoverX® cell lines and cell-based assays are based on the Enzyme Fragment Complementation Technology (EFC) technology. This patented technology provides drug discovery and development researchers the means to interrogate biomolecular reactions for advancing therapeutic drug screening and development programs. EFC is a homogeneous detection assay system that enables you to measure and rank ligand potencies, discover the MOA, perform binding and functional screens, identify novel compounds, and much more.
EFC has been used as a robust and reliable assay technology for decades in >1M programs including >250 stability and commercial release programs. Eurofins DiscoverX has developed numerous assay formats to interrogate the desired MOA of therapeutics such as PathHunter®, HitHunter®, KILR®, InCELL, and SPRINTer™. These assay formats are used from discovery through development into lot release testing and stability studies of many small molecule and biological therapeutics on the market today and within clinical trials.

EFC Technology Principle
EFC is based on two recombinant β-galactosidase (β-gal) enzyme fragments that act as an enzyme acceptor (EA) and an enzyme donor (ED). Separately, the fragments are inactive, but when combined, they form an active β-gal enzyme that hydrolyzes its substrate to produce a chemiluminescence signal.
