Automated systems and protocols for the routine preparation of a large number of screens and nanoliter crystallization droplets for vapor diffusion experiments are described and discussed.
Difficulty
advanced
Total time
~2–4 hours per screening experiment (depending on plate count and sample number)
Steps
1
Prepare 72 crystallization plates with screening kits
Use automated System 1 to fill 72 crystallization plates with commercial screening reagents. This automated preparation ensures consistent reagent distribution across multiple plates for routine high-throughput screening.
