DNA-Encoded Library (DEL) Services
Fast Screening of Billions of Small Molecule Compounds
DNA-Encoded Library (DEL) technology involves a novel affinity selection process that integrates chemistry, biology, bioinformatics and computational chemistry to facilitate a rapid drug discovery process, allowing access to more chemical space with lower cost.
In contrast to high throughput screening, DEL requires a very small amount of target protein and minimum assay development. More importantly, it disrupts the concept of “cost-per-well” and allows testing billions of compounds in one tube.
