A new quality control procedure ensures accurate compound and reagent delivery in miniaturized drug discovery assays. This standard operating procedure validates liquid handling instrumentation for reliable screening data.

Area of Science:

  • Drug Discovery and Development
  • Assay Development and Screening
  • Laboratory Automation and Instrumentation

Background:

  • The early drug discovery field increasingly relies on miniaturized assays to manage costs and competitive pressures.
  • Miniaturization necessitates advanced instrumentation, including nanodispensing and sophisticated detection systems.
  • Ensuring accurate compound and reagent delivery is crucial for data integrity in miniaturized assays.

Purpose of the Study:

  • To develop and implement a standard operating procedure (SOP) for liquid-handling quality control (QC).
  • To evaluate the performance of liquid handling instrumentation used in drug discovery assays.
  • To establish a method for harmonizing instrumentation usage and facilitating data exchange across research groups.

Main Methods:
