Area of Science:

• Structural Biology
• Biochemistry
• Crystallography

Background:

• Crystallization is crucial for protein structure determination.
• Traditional methods can be time-consuming and labor-intensive.
• Advancements in automation are needed for high-throughput screening.

Purpose of the Study:

• To describe a high-throughput crystallization workflow.
• To report on the implementation and experience with this workflow.
• To detail automated data acquisition and analysis for crystallization trials.

Main Methods:

• Nanolitre-scale sitting-drop vapour-diffusion experiments.
• Automated storage and imaging systems for 294 K trials.
• Manual imaging for 277 K trials, with data integrated into a laboratory information-management system (LIMS).

Main Results:

• Implementation of a high-throughput workflow for crystallization screening.
• Automated data harvesting, scoring by crystal recognition software, and web-based analysis.
• Experience gained from 592 crystallization projects using the described workflow.

Conclusions:

• The high-throughput workflow significantly enhances crystallization trial efficiency.
• Automated systems streamline data management and analysis.
• The reported experience provides valuable insights for structural biology laboratories.
