crystallisation campaigns

Methods & Expertise for Research Infrastructure

The crystallisation of a biomolecule represents a major challenge in the determination of its three-dimensional structure. The crystallisation robot enables the miniaturization of crystallisation campaigns to the nanolitre scale. This reduction enables an up to 100-fold reduction of the required protein, or conversely, a corresponding depth increase of the crystallization campaigns with identical protein usage. Importantly, this nanoliter robotics allow to carry out structural investigations on proteins, which can be produced at inherently low yield, e.g., membrane proteins. Finally, by its unique contamination-free working procedure the robot also qualifies for sensitive pipetting applications such as (epi) genomics.
