High-Throughput DNA-Encoded Libraries Affinity Selection Platform for Binder Identification with Solid Support...

Area of Science:

• Biochemistry
• Chemical Biology
• Drug Discovery

Background:

• DNA-encoded libraries (DELs) are powerful tools for identifying novel ligands.
• Affinity selection (AS) is the core method used in DELs to find binders.
• Current AS methods can face challenges in reproducibility and throughput.

Purpose of the Study:

• To develop a high-throughput, automated affinity selection (AS) platform for DNA-encoded libraries (DELs).
• To enhance the reproducibility and flexibility of AS processes in ligand identification.
• To create a platform compatible with industrial standards for DEL applications.

Main Methods:

• Development of a fully automated platform for high-throughput affinity selection.
• Implementation of two primary protein immobilization techniques: magnetic beads and resin tip columns.
• Configurable protocol options supporting diverse DEL types and experimental conditions for 96 simultaneous samples.

Main Results:

• The platform demonstrates high throughput and flexibility, accommodating various DELs and AS methods.
• It supports both magnetic beads and resin tip column immobilization for proteins.
• The system allows for routine DEL screens, covalent library screening, and protein immobilization validation.

Conclusions:

• The automated AS platform significantly improves the reproducibility of DEL binder identification.
• Its versatility makes it suitable for a wide range of applications in academic and industrial drug discovery.
• This technology offers a powerful instrument for advancing ligand identification using DELs.
