A new miniaturized ultra-high-throughput screening (uHTS) system was developed for drug discovery. This system uses novel confocal fluorescence readers to achieve high data quality in small assay volumes, enabling efficient screening of compound libraries.

Area of Science:

  • Biotechnology
  • Pharmaceutical Science
  • Analytical Chemistry

Background:

  • The increasing size of compound libraries and new drug targets necessitate advancements in screening technologies.
  • Existing ultra-high-throughput screening (uHTS) systems require improvements in data quality and operational reliability for miniaturized assays.

Purpose of the Study:

  • To develop a modular, fully integrated system for miniaturized uHTS.
  • To achieve high data quality in small assay volumes (1-4 microL) with reliable, unattended operation.
  • To design and validate novel confocal fluorescence readers for diverse assay types.

Main Methods:

  • Development of a modular, integrated uHTS system.
  • Design of two confocal fluorescence readers: a 4-channel parallel reader and an imaging reader.
