Automated assay optimization (AAO) integrates statistics, biochemistry, and robotics to overcome high throughput screening bottlenecks. This novel process enhances assay performance and reduces optimization time for drug discovery.

Area of Science:

  • Biochemistry
  • Robotics
  • Statistics
  • Drug Discovery

Background:

  • High throughput screening (HTS) has accelerated compound screening but revealed bottlenecks in assay optimization.
  • Manual assay optimization struggles with the demands of robotic HTS, facing issues like protein aggregation and ligand instability.
  • Existing methods often require extensive optimization to ensure assay robustness for automated systems.

Purpose of the Study:

  • To develop a novel process for reducing assay optimization bottlenecks in high throughput screening.
  • To integrate statistical, biochemical, and robotic principles for enhanced assay development.
  • To improve the efficiency and performance of assays used in drug discovery pipelines.

Main Methods:

  • Developed automated assay optimization (AAO) by unifying statistics, biochemistry, and robotics.
  • Utilized advanced robotics for rapid, random access optimization experiments.
  • Applied the AAO process to radioligand binding and enzymatic assays.

    • Main Results:

    • Achieved optimized assay conditions that were often composites of variables not identifiable through independent analysis.
    • Demonstrated significant improvements in both time and assay performance compared to traditional methods.
    • Successfully applied AAO to diverse assay formats, including radioligand binding and enzymatic assays.

    Conclusions:

    • Automated assay optimization (AAO) effectively addresses the assay optimization bottleneck in HTS.
    • The integration of smart robotics and automated liquid handling streamlines assay development.
    • AAO is an invaluable tool for maintaining high-quality data and meeting increasing HTS demands in drug discovery.
