Implementing multilevel dynamic scheduling for a highly flexible 5-rail high throughput screening system.

Area of Science:

• Automation and Robotics in Drug Discovery
• High-Throughput Screening (HTS) Technologies
• Laboratory Information Management Systems (LIMS)

Background:

• Drug screening processes face bottlenecks in sample management, hit picking, and reagent handling.
• Manual sample and reagent feeding limits the throughput of large HTS departments.
• Instrument malfunctions lead to significant loss of plates and reagents.

Purpose of the Study:

• To address bottlenecks in HTS by automating sample management and integrating sample storage.
• To improve efficiency and reduce reagent waste in automated drug screening.
• To design a robust automated system with error handling for HTS.

Main Methods:

• Development of an automated online sample repository system feeding multiple assaying systems.
• Implementation of online data analysis for automated hit picking and confirmation.
• Integration of redundant assaying systems for enhanced error handling.
• Selection and implementation of sophisticated scheduler/controller software for real-time system coordination.

Main Results:

• The integrated system automates sample management, reducing manual labor.
• Online data analysis enables automated hit picking and confirmation.
• Redundant assaying systems mitigate losses due to instrument malfunctions.
• Sophisticated software ensures real-time coordination of complex robotic environments.

Conclusions:

• Automating sample management and integrating sample stores significantly improves HTS efficiency.
• Redundancy and advanced control software are crucial for reliable and high-throughput drug screening.
• The designed system effectively overcomes common bottlenecks in automated drug discovery pipelines.
