Aurigene offers state-of-the-art DNA Encoded Library (DEL) screening services for small molecules, in strategic collaboration with Vipergen, to accelerate innovation in drug discovery by increasing success rates and reducing timelines through screening a billion+ small-molecule compounds.
The unique platform enables screening not only using a purified drug target protein but also in a living cell. Screening in a living cell mimics the physiological conditions more accurately.
The collaboration aims to co-market and offer DEL screening technologies to global customers as a standalone service or as an integrated drug discovery service. Combining Vipergen’s DEL technology with Aurigene’s 20+ years of experience in synthesis, protein generation, assay development, and testing of compounds in both in-vitro & in-vivo setup enables us to service the customer end-to-end.
Leverages Cellular Binder Trap Enrichment®(cBTE) technology. It is the first and only technology for screening of DELs inside a living cell.
The advantage of screening inside a cell includes:
uses homogeneous screening method, Binder Trap Enrichment® (BTE), water-in-oil emulsion technology to isolate individual ligand-target complexes
The specific benefits of BTE include:
The Yoctoreactor libraries containing hundreds of millions of DNA-encoded drug-like small molecules are synthesized in a single tube-format by drawing on the self-assembly of complementary DNA into DNA junctions. Chemical building blocks (BBs) are brought into close proximity which facilitates chemical reaction and the attached DNA ultimately encodes the final product.
The overall design has favorable implications for the scope and reliability of the chemistry, the stability of the structure, and, ultimately, the capability for addressing the most challenging targets. 100% correspondence between code and synthesized compound is ensured by purification steps using the DNA as purification handle after each chemical step.

A homogeneous screening method for DELs which uses water-in-oil emulsion technology to isolate individual ligand-target complexes. Ligands to a protein target are identified by trapping binding pairs (DNA-labelled protein target and DEL ligand) in emulsion droplets during dissociation dominated kinetics. Once trapped, the target and ligand DNA are joined by ligation, thus preserving the binding information.
The identified potential hits from the screening will be dedicated to the customer and removed from the library for other customers.
